i mean. if the cat and dog live together then they should be fine with each other really. and as for the pitbull. only be afraid of the dog if you think the owner trained it to be mean. dogs just like most other intelligent animals react on instinct and training. if you dont attack the dog instinct wont kick in and only poor training will hurt you. at which point why would you go there? and animals pick up on your fear easily. leading them to sometimes display dominance over you.
