Do cats and dogs work independently?

Hello to everyone. I’m excited to join this forum; it’s more than just “interested.” Carl, my pug puppy, has some questions for you guys My question I’d like to know if Carl will be okay with me adopting a cat. Do cats and dogs work independently? I discovered a munchkin breeder online and went to their cattery. They were extremely friendly, and I think I need to adopt one of their munchkin kittens. Please, guy, assist me! Also, please assist me in checking them online. You can also make a visit to ( Meyland Cattery) just search on Google
