If a cat accidentally eats a gecko, the owner must first observe its reaction. Once vomiting or diarrhea occurs, it needs to go to a pet hospital for treatment immediately. But generally speaking, there is no big problem for cats to eat geckos, because cats often catch some insects or small reptiles. Some cats just play to relieve their boredom, and some will eat them in the end. This is also the reason for cats. Due to their hunting nature, owners only need to deworm their cats regularly, because there may be parasites in the animal's body.
