Toads and cats
It may be useful to know that toads do have a venom that they can secrete when they feel threatened. If a cat licks or bites a toad, they can ingest the venom from the toad's glands on their back. They can then start to salivate a lot and become nauseous and tired.
What should I do?
Keep your cat under observation
Rinse out its mouth as soon as possible
Check the mouth for signs of injury
Look for material stuck between the teeth
Do I need to see a vet?
Usually this condition is harmless and will pass in a few hours to a day. If the cat is not severely affected, you may want to wait before visiting the vet. Keep an eye on your cat and consult a vet if your cat's general condition deteriorates significantly.
