I would absolutely suggest against getting a cat until you find your snake. Here is a recent incident of a cat finding the snake before the owner did:
The snake was gravid. It was "found" by the cat. This resulted in 2 spinal fractures, (one of which is barely hanging on by the spinal cord) and 2 punctured eggs. The snake had a very hard time passing them. She did pass them eventually, but I believe it took about a wee. Still no idea if she will recover from this, as the chance of infection, ESPECIALLY from a cat bite, is very, very high. Anyways:
I had lots of advice involving people's cats finding their snake.
It's an 8 week old kitten.
Considering my three Sight Hounds and a Dobermann, I'd think a kitten is the least of his worries.
