1) I think the dog and cat would actually talk to each other and see the similarities they have with each other, which would then let them relate and become friends(hopefully)
2) It was really cool being in the perspective of a dog and the dog's reaction to other animals. I never really thought how a dog might think about cats and vice versa. Then, to have the dog be in the perspective of the cat was even better and the dog started to see the cat wasn't as bad as it thought it was.
