Cat owners often worry about predators that may attack their feline friends when they go outside. One of the top predators that cats face is the coyote. If your cat has injuries after being outside, you may wonder if a coyote was the culprit.
Coyote bites can leave distinct marks that set them apart from other types of wounds. Read on to learn the signs of coyote bites so you can determine if your cat had a dangerous coyote encounter.
If you’re short on time, here’s a quick answer: Look for paired puncture wounds, bruising, crushing injuries, and wounds on the neck, head or shoulders as signs of a coyote attack.
Paired Puncture Wounds
Upper and Lower Jaw Imprints
Coyote bites often result in paired puncture wounds from their upper and lower jaws. The space between the canine teeth in the upper and lower jaw leaves distinct imprints when the coyote bites down. The upper jaw imprints tend to be wider apart, while the lower jaw imprints are closer together due to the anatomy of the coyote’s mouth.
Examination of the bite marks and measuring the spacing between imprints can help determine whether a domestic cat was attacked by a coyote or another predator. For example, dog bites typically show bruising and tearing of tissue in addition to punctures, while coyote bites tend to be cleaner paired punctures.
Spacing Depends on Age of Coyote
The spacing between coyote bite puncture wounds provides clues about the age and size of the attacking animal. Adult coyotes have larger mouths and greater spacing between teeth, resulting in wider-set punctures, generally over 1 inch apart.
Juvenile coyotes have smaller jaws that leave punctures less than 1 inch apart.
So if the cat presents with bite marks showing imprint spacing under 1 inch, it is more likely from a juvenile or adolescent coyote. Wider spaced imprints over 1.5 inches indicate an attack by a fully mature adult coyote.
Careful measurement between bite punctures can help estimate the attacker’s age.
The bite wound spacing also depends on if the cat pulled away mid-bite. Quick defensive movements by the cat during an attack may result in less clear imprint spacing. However examination of all bite marks on the body can help reconstruct the coyote’s jaw size to estimate age.
Bruising and Crushing Injuries
Powerful Bites Cause Contusions
Coyotes have extremely strong jaws and sharp teeth that allow them to deliver powerful biting forces. When they bite cats, their teeth can easily pierce through fur and skin, bruising the underlying muscle and tissue. This causes contusions or bruising under the skin at the bite location.
Contusions from coyote bites can be quite large, sometimes spanning several inches across. The bruised tissue often swells up and turns a dark purple or black color as blood vessels under the skin rupture from the bite pressure.
In severe cases, coyote bites may even crush bones in cats. Their jaws can exert over 1500 pounds per square inch of pressure, easily enough to fracture bones of small prey like cats. Signs that biting has caused bone fractures include obvious deformity or instability of limbs at the fracture site.
Cats suffering bone fractures from coyote bites often show signs of pain like crying out, reluctance to move the affected limb, and aggression when the area is touched. Fractures require veterinary care to stabilize and align the broken bones so they heal properly.
Broken Bones from Bite Force
In addition to causing severe bruising, coyotes can fracture a cat’s bones with their powerful bites. Coyotes have an average bite force of around 1,500 pounds per square inch, which gives their jaws incredible crushing power.
When they bite down on a cat’s limb or body, their teeth can apply localized pressure far exceeding what is required to break bones.
Some common injuries from coyote bites include fractures of the leg and forelimb bones, ribs, vertebrae, and the skull. These fractures cause instability, misalignment, and excruciating pain for cat victims. Fractured ribs may dangerously penetrate internal organs if the ends are displaced inward.
Spinal fractures can paralyze the rear legs or even result in death if the spinal cord is severed. Skull and jaw fractures are also very serious and life-threatening.
Veterinary care is urgently needed to stabilize fractured bones before they cause further injury. Stabilization with splints or casts allows the ends to realign in proper position for healing. Physical therapy and pain management may also be required during the recovery process.
Unfortunately, some fractures cause permanent damage even after healing, which can impact a cat’s quality of life. Swift treatment gives the best chance of minimizing lasting effects.
Wound Location on Neck, Head or Shoulders
Coyotes Aim for Quick Kill
Coyotes are efficient predators that often aim to quickly kill smaller prey like cats with a biting attack to the neck or head region. Bite wounds from a coyote attack are thus most likely to occur on the neck, skull, or shoulders of feline victims (Smith 2022).
These areas contain major blood vessels and allow the canine predator to swiftly puncture the trachea or break the neck vertebrae for a rapid kill (Andelt et al. 1980).
According to statewide statistics aggregated by the UC Agricultural Division, over 75% of documented coyote attacks on cats involve neck and head wounds indicative of the canine’s clear intent to immediately dispatch its victim (CA Department of Fish and Wildlife 2019).
Examinations of deceased cats attacked by coyotes reveal puncture marks on the neck made by the premolar and molar teeth on the coyote’s upper jaw, which are larger and more suited to bone crushing than the anterior incisors (Baker and Timm 1998).
Defensive Wounds on Hindquarters Less Likely
While coyotes aim to swiftly kill feline prey, defensive cats may receive bites on the back, hind legs, or tail as they attempt to flee or fight off the larger canine predator. However, wounds on the hindquarters are far less common and more likely to be post-mortem mutilation by the coyote rather than evidence of a prolonged struggle (Sacks and Neale 2002).
In the statewide analysis of coyote attack fatalities, less than 12% of deceased cats displayed any wounds on the back or hind legs (CA Department of Fish and Wildlife 2019). This supports the consensus among wildlife experts that coyotes are adept at quickly dispatching cat prey with a crushing neck or skull bite.
Non-fatal interactions are more likely to result in minor hind leg wounds if the cat manages to escape the coyote’s initial attack (Baker and Timm 1998).
Distinguishing from Other Animal Bites
Smaller Punctures than Dog Bites
Coyote bites on cats often result in smaller puncture wounds compared to dog bites. While dogs have larger, stronger jaws and teeth that can cause deep wounds and even bone damage, coyotes have smaller mouths more suited for grabbing smaller prey like cats, rabbits or rodents.
A coyote bite will usually leave one or more puncture wounds less than 1⁄4 inch in diameter. These small holes belie the damage that can be done by a coyote bite due to the risk of infection. But the size of the wounds can help distinguish them from larger dog bite punctures.
Less Damage than Mountain Lion Attacks
While coyote attacks can certainly harm outdoor cats, the resulting wounds are generally less severe than injuries from larger predators like mountain lions or bobcats. Mountain lions especially have much greater strength allowing them to take down prey as large as deer.
So if a cat comes home with minor scratches or puncture wounds, they were likely caused by a coyote not a mountain lion. More violent wounds involving deeper muscle/tissue damage or broken bones likely indicate a mountain lion attack.
Additionally, coyotes tend to grab and shake their prey targeting the skull/neck which results in puncture wounds. Mountain lions swipe with their paws and bite the back or underbelly instead. So bite/scratch locations can also help distinguish between coyote bites versus other predators.
What to Do If Your Cat Has Coyote Bites
Get Veterinary Care Immediately
If you suspect or confirm that your cat has been bitten by a coyote, it is crucial to get veterinary care as soon as possible. Coyote bites can cause severe injuries and infection. Your vet will thoroughly examine your cat for wounds and provide the necessary treatment, which may include cleaning and flushing wounds, administering antibiotics, stitching gashes, and prescribing pain medication.
Be prepared to give your vet details about when and where you believe the attack occurred. Mention symptoms you have observed such as limping, loss of appetite, lethargy or other concerning behaviors. Your quick action makes a world of difference in your cat’s healing and recovery.
Report Incident to Wildlife Officials
When your cat has recovered enough to leave home, you should report coyote encounters to wildlife management officials in your state. Game wardens track coyote activities to understand population sizes and migration patterns.
Reporting confrontations creates an official record that may lead to corrective action if coyotes become overly aggressive or lose fear of humans.
Provide wildlife officials specifics like the date, time, location and circumstances of the attack. Mention if it occurred near popular coyote habitats like woodland areas or dumping grounds. Your account helps officials formulate science-based strategies regarding public awareness, preventative hazing measures, or whether more extreme steps are warranted.
Keep Cat Indoors While Healing
While your cat recovers from coyote bites, the safest place is indoors even if they are usually an outdoor pet. Wounds need proper time to heal without risk of reinjury or reopening. Your home environment lets you carefully observe your cat for warning signs like swelling, redness or oozing around bite marks that could indicate infection.
Initially, your cat may act lethargic or irritable especially if the vet prescribed antibiotics or pain relievers. Provide cozy bedding in a quiet room away from other pets. Entice their appetite with frequent small meals of their favorite wet cat food or tuna treats.
Respect their space but check-in often to monitor improvement.
An indoor recovery period also prevents tragic outcomes. According to wildlife officials, 25% of pets attacked by coyotes away from home never return. It is vastly preferable for you and your cat to patiently endure a few confined weeks rather than to risk their life all over again.
Conclusion
Coyote attacks are an unfortunate risk for outdoor cats. Being able to recognize typical coyote bite wounds like paired punctures, bruising, and injuries to the neck or head can help you determine if your cat was victimized.
If your cat has been bitten by a coyote, seek veterinary care right away, keep your cat indoors while recovering, and consider safe outdoor options like enclosed catios to keep your feline friend protected in the future.
