My Cat Ate a Lizard

My cat ate a lizard

Our domestic feline companions, despite their luxurious indoor lifestyle, often exhibit instinctual behaviors harking back to their wild ancestors. Hunting is one such behavior, with prey often including birds, mice, and the occasional reptile like a lizard. However, the question on many pet owners’ minds is, “What should I do if my cat ate a lizard?” This article addresses this concern, detailing potential side effects, reasons behind the behavior, and the toxicity of lizards.

Why Do Cats Eat Lizards?

Cats, even those pampered with commercial cat food, have an inherent predator instinct. This ancestral hunting drive is often the reason why cats chase and catch smaller creatures such as lizards. Even though domestic cats don’t need to hunt for survival, their instinct compels them to stalk, pounce, and sometimes devour such prey. This behavior not only satiates their instinctual need but also serves as a form of environmental enrichment and exercise.

What Should I Do If My Cat Ate a Lizard?

If you discover that your cat has eaten a lizard, the first step is to stay calm. While there are potential risks associated with consuming a lizard, many cats will be unaffected. Remove any remaining parts of the lizard from the cat’s environment to prevent further ingestion.

Observe your cat closely for any signs of distress or illness over the next 24-48 hours. As with any foreign ingestion, monitor for general signs of discomfort such as loss of appetite, lethargy, vomiting, diarrhea, or changes in behavior.

If you observe any of these symptoms, it is imperative to seek immediate veterinary care. It can be beneficial to take along any remnants of the lizard for identification, as this could aid in diagnosing potential issues.

Are Lizards Poisonous to Eat?

Most lizards are not poisonous to cats, but it’s important to note the distinction between poisonous and venomous. A poisonous creature delivers toxins when eaten, while a venomous one injects venom through a bite or sting. There are very few venomous lizards, and most cats are unlikely to encounter one, especially in an urban setting.

However, consuming lizards does pose other potential health risks. Parasites are one such concern. Some lizards carry parasites like worms, which can infect cats if ingested. Lizards may also carry bacteria like Salmonella, which can lead to gastrointestinal issues in cats.

Symptoms of Lizard Venom Toxicity

In the unlikely event that your cat catches and consumes a venomous lizard, there are specific symptoms to watch out for. These could include severe pain, weakness, rapid breathing, irregular heartbeat, and in rare cases, paralysis. If your cat shows any of these symptoms, seek emergency veterinary care immediately.

Remember, however, that venomous lizards are rare and generally not found in urban or suburban areas where most domestic cats live.

What are the Side Effects of a Cat Eating a Lizard?

Assuming that the lizard isn’t venomous, and the cat is not allergic or sensitive, the majority of felines who eat a lizard will experience no severe side effects. As mentioned before, potential issues may arise from ingested parasites or bacteria.

Gastrointestinal upset, marked by symptoms like vomiting, diarrhea, or loss of appetite, is the most common side effect of eating a lizard. More seriously, if your cat ingests a parasite from the lizard, they may develop a parasitic infection, which can cause a range of symptoms from mild diarrhea to significant weight loss.


While our feline companions’ hunting behavior can be concerning, especially when the prey is a potentially risky lizard, it’s essential to remember that serious issues are relatively rare. Should your cat eat a lizard, monitor their behavior and look for any changes in health. If your cat shows any signs of illness or distress, consult with a vet immediately.

While most cats can safely digest their little reptile snack, a responsible cat owner should always be ready to intervene if the adventure turns out less pleasant than expected. After all, while it’s part of a cat’s nature to be a predator, it’s part of our human nature to ensure our pets stay safe and healthy.
