Snakes get a bad rap: They’re typically unlikely to bite unless surprised or on the defensive. Nevertheless, this slithery species is seen as one of the most fearsome in the animal kingdom—even felines agree, which is why cats hiss to imitate snakes! But what if you come across a snake bite on a cat? Learn what to look for and how to treat your pet in the unlikely event that this happens.
Cat snake bite symptoms: Non-venomous
Non-venomous snake bites on cats are much more common than venomous, but these kinds of bites can still be dangerous. Cats are most likely to be bit by a snake on their legs. Typically (because there are always exceptions), non-venomous snake bites are horseshoe- or U-shaped and may be accompanied by pain and bleeding—but not swelling.
Cat snake bite symptoms: Venomous
On the other hand, venomous snake bites typically appear as two puncture marks. This type of bite will likely be accompanied by pain and swelling. Other symptoms to watch for in your pet include:
- Bleeding
- Pale or white gums
- Rapid heartbeat
- Rapid breathing or difficulty breathing
- Vomiting and/or diarrhea
- Weakness
- Drooping eyelids
- Dilated pupils
- Incoordination
- Paralysis
- Convulsions
How to treat a snake bite on a cat
If you notice a bite mark or any of the above symptoms on your cat (but didn’t observe the attack itself), we recommend taking your cat to an animal hospital right away. Treatment should begin as soon as possible after the bite.
- Approach your cat carefully. If your cat is nervous or anxious, restrain him if necessary.
- If possible, clip the hair from the bite area on your cat.
- Flush the area thoroughly with sterile saline solution or mild soap and water.
- Transport your cat to the veterinarian immediately.
If you observed your cat being bit by a snake, try to take note of what kind of snake it is (for instance, rattlesnake) or any of its identifying marks. If possible, snap a photo of the snake. Do NOT approach the snake unless you are certain it is deceased. If you’re able to bag the dead snake (wear gloves), bring it along with your cat to the animal hospital.
The veterinarian will want to know any information you have about the snake, where the attack took place, and where and how long since your cat was bit. A venom test kit, blood work, and cultures may be performed to identify the snake and determine treatment. The vet may need to administer antivenom, IV fluids, feeding tubes, and oxygen, depending on the severity of the situation. Unfortunately, if treatment for a venomous snake bite on a cat isn’t immediate, the bite is often fatal.
