Question

What would you do if your cat starting acting like a dog and your dog started acting like a cat?

Answer 1

introduce a new pet, like a bird.

Answer 2

 I'm not sure, lol. My mom actually brought a puppy a few months younger than my cat into the household. It's been a few months and the puppy actually learns behavior from the cat. The puppy will jump very high or over gates because she has seen my cat do so. :D
