Oh my cat is a total jerk (I love him, but he just is). He barely tolerates humans just because we're big, and he acts aggressive towards any other animals. My grandmother can't bring her dogs over because one animal would certainly die (and I don't think it would be the cat...). I just don't know if a smaller, less threatening animal would be different? Most likely not, I'm just concerned about exactly HOW strict I need to keep safety levels, like whether I need to put the cat outside/in a closed-off room if I want to bring the snake out of my bedroom.
That's enough for me to advise: keep the cat FAR away from the snake. Not worth taking any chances. Both cats and snakes are super quick and it's NOT worth taking ANY chances.
