I'm thinking I need a mental health pet. I want a dog but they're expensive so I've been thinking about a cat. My sister says I should get a ragdoll cat but I looked online and they go for $2,000! I can't afford that. I need vet money and food money etc of course. I'd like a rescue greyhound but as I say they can be vet heavy- Or so I'm guessing. Any ideas, suggestion, or words to the wise?
