Who told you that cat and dog can’t be friends? My family and I had this cat and dog for almost 2 years now and all I can say is they are pretty good. They sometimes make fun with each other like when my dog is jealous to my cat, she seems to be papansin, start a fight with my cat like grabbing the cat’s head. They even share food huh. I think they’re like best friends that at the end of the day even they had a fight, they still choose to be friends and forgive each other. That’s all guys. Have a good day!
