Luckily for our feline friends, snake bites in cats are relatively rare compared with their canine counterparts. Cats tend to be savvier than your average bouncy puppy! However, when it does happen, a snake bite in a cat is a true emergency. So, especially if you live in an area inhabited by snakes, it is important to know the signs to watch for and what to do next.


Venomous Snakes in the USA

There are around 21 species of venomous snake found in the United States. Most venomous snake bites in the US are from Pit Vipers; which includes Rattlesnakes, Cottonmouths, and Copperhead snakes. The other species to watch out for are Coral snakes, although these are generally only found in the Southern edge of the USA. Pit Vipers can be identified by their diamond-shaped head, oval-shaped pupils, and a pit between their eyes and nose. They tend to be active in the warmer months.

This depends on the snake. Nonvenomous snakes can cause nasty and painful bruising but rarely cause any serious problems. Venomous snake bites, on the other hand, are a true emergency and can be fatal. Coral snakes release a neurotoxin that paralyzes the breathing system. When Pit Vipers bite, releasing venom is a voluntary action, meaning that they can control it. This means that some bites from venomous snakes are ‘dry bites’. Dry bites don’t actually contain any, or minimal, venom. It is impossible to tell by looking though, so it is safest to always assume that a bite contains venom and treat it as an emergency.

What are the Symptoms of a Snakebite in a Cat?

As we all know, our feline friends like to explore and we aren’t often able to see what they get up to! So, you may not see your cat being bitten by a snake. This means that it is important to know what the symptoms of a snake bite are. How do you tell if your cat has been bitten by a snake? Here are the signs to watch for.

Non-venomous snake bite symptoms include bruising and swelling in a localized area. Your cat may be lame if the bite is on a limb. Keep in mind that you may not always see distinct fang marks, as these may be hidden by the swelling.

Venomous snake bite symptoms in a cat come on quickly, usually within an hour of being bitten. However, Coral snakebites can take up to 18 hours to show symptoms. Snake bites are most common on a cat’s head and neck or legs. Symptoms will vary, depending on the type of snake and how much venom was injected. They include:

  • Painful swelling and/or bruising around the bite, which tends to worsen and spread quickly
  • Bleeding, or bloody discharge, from the bite
  • Fang marks
  • Limping (if bitten on a leg)
  • Signs of pain/distress such as being agitated
  • Tiredness (lethargy)
  • Drooling
  • Sickness and/or diarrhea
  • Fast, shallow breathing
  • Wobbly gait
  • Paralysis
  • Seizures
  • Uncontrolled bleeding
  • Although not visible symptoms, snake bites can result in damage to the heart, kidneys, and liver

If your cat shows any of these symptoms, or you have seen them being bitten by a snake, contact your veterinarian as an emergency.

What Should I Do If My Cat is Bitten by a Snake?

If you know or suspect that your cat has been bitten by a snake, you should treat this as an emergency. Do not try to handle or harm the snake. If possible, take a photo of the snake, but do not risk getting too close or go looking for it.

Leave the wound alone! There is much outdated advice and many myths available online about first aid treatment for a snake bite. You should not: attempt to suck out the venom or open the wound; apply a tourniquet; apply ice or hot packs; nor use electric shock. They have been proven to be ineffective (some are even dangerous) and attempting them will delay getting your cat to a veterinarian. The most important actions are

  1. Keep your cat as calm and still as possible, this may reduce the spread of venom. Get them into their pet carrier as soon as possible.
  2. Call your veterinarian to tell them that you are on your way. If possible, let them know:
    • a description or photo of the snake
    • when the bite occurred, or could possibly have occurred
    • any symptoms you have noticed.

What is the Treatment for a Snake Bite in a Cat?

Treatment will depend on the snake, the location of the bite, and if the bite was venomous. Luckily, antivenom is available in most cases. When appropriate, your veterinarian will give this as soon as possible. Regardless of whether antivenom is given, your veterinarian will advise admitting your cat to hospital for observation for a minimum of 8 hours, often 24-48 hours. This is to monitor for symptoms, progression and to monitor for any allergic reaction to the antivenom, if given. Thankfully allergic reactions are rare.

Your veterinarian will give strong pain relief. They may shave and flush the wound. Treatment may also include blood samples to look for internal damage, a fluid drip, and antihistamine or steroid medication.

In more severe cases where there is uncontrolled bleeding, blood transfusions may be needed. If your cat is seizuring, your veterinarian will give drugs to try to stop the seizures. Rarely, in extreme cases, your cat may need to be intubated to help them breathe.

My Cat was Bitten by a Snake; Will They be OK?

If your cat was bitten by a non-venomous snake, then most likely yes. Possible complications include infection of the wound, but serious complications are rare.

For venomous bites, when treatment with antivenom is given promptly (within 1-4 hours), chances of survival are good. So prompt treatment really is key here. The outcome of a snake bite in your cat will depend on several factors: the type of snake; the location of the bite; the number of bites; the weight of your cat; how quickly treatment was started; and the underlying health of your cat. Bites to the chest or tummy area tend to have poorer outcomes.

Unfortunately, snake bites can be fatal. With Coral snakes, if a cat survives, then they should make a full recovery. In contrast, Pit Viper snake bites can cause more long-lasting damage such as tissue death around the wound, which may need extensive surgery.

How Can I Prevent Snake Bites in My Cat?

Snake bites in cats are much harder to prevent than in dogs, since as cat parents you have much less control over where they roam! If you live in an area heavily populated with snakes, you might want to consider keeping your cat indoors during the snakes’ peak activity months (usually summer). For example, rattlesnakes are nocturnal, so keeping your cat in at night can help to reduce the risk. It may help to keep your garden clear of areas a snake may like to hide in; such as piles of wood, leaves, or rocks.
