I already own a dog and really want to adopt a cat from a shelter. I know getting a cat to be with a dog is not very orthodox, but I really wanted a cat to begin with, and I feel like dogs are more expensive to own, so having 2 dogs would be a bit too much for my budget. I feel like owning a cat would be better for me. So my question is, do you know how much extra I would probably spend owning a cat along with my dog? If any of you own both a dog and a cat please let me know how it is!
