My cats are fixed & indoor only. I also don't have to brush and play with them everyday. One of the perks of having two cats is they will play with each other. ;)
I have 1 dog, 2 cats, and I've been keeping chickens for the past 3 years. So trust me, I know what I'm talking about here.
From hardest to easiest:
1. Dogs
2. Chickens
3. Cats
