I've "consolidated" my collection lol. Right now, living with me, I only have three. However, 4 of my cats live with my mom, and one lives with my dad. I'm also, when space allows, a "foster mom" for 3 local shelters. When I lived in a bigger house with my ex, I had 21 at one point.
My ideal number is 5. As soon as HMA and I are out of our apartment, I get to add two more babies. I'm so excited!
