My cat had a bot. Saw the vet take it out
A stray cat turned up at my house with a botfly larva in her throat. It was so horrible. The thing would sometimes poke its head out. I took her to the vet and she removed it. She said it was called a “wolve”. I’m so sorry that happened to your poor kitty.
The ones that get into cats (and dogs and squirrels and rabbits, etc.) are larvae of a different genus of botfly from the “bots” that infest horses. The ones in horses are inside their stomachs, and there can be gobs and gobs of them.
