Cats are known to catch and even eat lizards, but luckily, most lizards are harmless. They shouldn’t cause any problems for your cat, though some may cause an upset stomach simply because your cat isn’t used to eating them. It isn’t odd for cats to experience minor digestive issues when eating any whole animal.

However, that doesn’t mean that all lizards are entirely safe. Several situations may lead to problems. For instance, some lizards may contain parasites, which can be transferred to your feline. Sometimes, your cat may accidentally eat a poisonous lizard, which isn’t completely unheard of.

Therefore, while most lizards are safe, some may be dangerous. Here’s what you need to know if you suspect your feline may have eaten a lizard.

Liver Flukes in Cats

Lizards are well-known for containing a particular type of parasite called a liver fluke. When your cat eats the lizard, these parasites are then transferred to them, which can cause some severe damage. While these liver flukes are entirely harmless to lizards, they can cause severe problems for cats and other mammals.

After a cat eats an infected lizard, the flukes will travel to your cat’s liver, as well as their gallbladder. It takes about 8 to 12 weeks for these flukes to mature, and they typically don’t cause problems until then. However, mature flukes can cause fatal liver inflammation and block bile ducts, causing toxic bile to build up in the liver.

Therefore, you likely won’t notice symptoms until a few months after the lizard has been eaten.

Symptoms are usually related to digestion, such as vomiting and diarrhea. Loss of appetite, weight loss, and fever are also not uncommon. In severe cases, your cat may experience jaundice, enlarged liver, abdominal distention, and lethargy.

These liver flukes are most common in the southern U.S. states and Hawaii. However, they can technically occur anywhere. These flukes are specifically evolved to be ingested by cats—it’s part of their lifecycle. Therefore, a cat’s risk of infection when eating lizards is relatively high.

Often, cats will need to be hospitalized for a period to be medicated and stabilized. Usually, antibiotics are used to prevent opportunistic infections, which can cause further damage. Even after your cat has recovered, your vet will likely want to check their liver enzymes occasionally to ensure that their liver is holding up.

While many cats make a full recovery, it isn’t odd for some to have lasting liver damage.

The only way to prevent liver flukes is to keep your cat indoors where they cannot consume lizards. If your cat lives outside, you may want to provide an antiparasitic medication every three months or so to prevent infections. Speak with your veterinarian about the occurrence of liver flukes in your area.

Toxic Reptiles

Even if your feline doesn’t get liver flukes, there is the possibility that the reptiles they consume are toxic. There are quite a few lizards with toxic skin, though these are most common in tropical regions. If your cat even licks this lizard, it can cause serious problems.

Typically, the first symptom you notice is excessive salivation. Usually, it is a lot of drool, so it isn’t a symptom that pet owners usually miss. However, just because your cat is drooling doesn’t mean that you should rush them to the vet. This is the most minor symptom and can occur with little exposure. Slowly flushing your cat’s mouth out with water may be enough to reduce salivation.

If your feline’s eyes dilate or they start to experience seizures, seek veterinary care immediately.

With that said, many different lizards have different toxins, and can cause different symptoms. For instance, newts produce a neurotoxin that can cause heart attacks and death. There usually isn’t much warning, so you should seek veterinary attention right away.

How to Protect Your Cat from Reptiles

While most reptiles are harmless, there are enough potential problems that you should ideally prevent your cat from interacting with them. Preferably, it would help if you keep your cat indoors. Unless you have wild, toxic lizards wandering about in your house, indoor cats should be completely safe from these potential illnesses.

If you allow your cat outside, it is best to watch them and intervene if you see them playing with a lizard. A fenced-in patio is also a great option, though lizards can still get through the small cracks at the bottom. Adding a mesh screen around the bottom may prevent this.

Keep an eye on your cat’s behavior at all times, especially in the warmer months when lizards are more common. If you notice any of the above symptoms, you should seek veterinary help as quickly as possible.

Of course, if you have pet lizards, you should keep them out of reach. Remember, liver flukes do not harm lizards, so your pet may have parasites without you knowing.

In the end, there is no definite way to keep your cat from eating a lizard. Outdoor cats are obviously at a higher risk since they may encounter lizards more often. However, even indoor cats can escape and catch a lizard—or a lizard may find their way into your home and then get eaten by your cat.

Should I Let My Cat Eat Lizards?

Cats are hunters by nature. So, it isn’t odd for owners to wonder if they should even care about their cat eating lizards.

Does My Cat Need to Go to a Vet if They Eat a Lizard?

If you see your cat with a lizard, there is no reason to rush off to the vet, usually. Keep an eye on your cat for symptoms of liver flukes and toxic reactions to the lizard they consumed.

The only difference is if the cat consumed a lizard that you know is toxic. In this case, contact your vet right away and identify the lizard and the time that your cat ate it.

Remember, liver flukes take a very long time to produce symptoms in your cat. In some cases, your vet may be able to provide medication to clear out the flukes before they cause problems. If your cat regularly eats lizards, you should call your veterinarian to ask about any preventative medication they may be able to take.

Most lizards are harmless, and your cat should be just fine after eating one. You typically only have to worry if you’re in an area where liver flukes are endemic or your cat begins to show worrisome symptoms.

If your cat is allowed access outside, it’s not unusual for them to hunt lizards and occasionally catch one. Lizards are entirely harmless and don’t give cats any problems in most cases. However, some can cause severe problems for cats.

For instance, some lizards are toxic. Even licking them can potentially cause a cat to ingest poison. On other occasions, the lizard may be infected with a parasite called liver flukes, which they will then pass onto your cat.

Either way, while eating lizards is usually safe, this isn’t always the case. You should be cautious regarding your cat eating lizards, and reach out to your veterinarian if your cat is experiencing symptoms after they ingest one.
