I absolutely talk to all my pets, whether it be my dogs, cat, or horses. I definitely think my dogs and horses listen a lot better to me talking than my cat does, but my cat notices when I am talking to her and usually reacts from it. I think it's completely normal to talk to your animals, and even talk for them (which I know I do a lot)! I have a friend who always make fun of how I "baby talk" with all my animals, but oh well, they are my babies so I guess there's no harm there. Anyways, you're definitely not nutty for talking to your animals, they are your family!
