“I’m pretty passionate about not having free-roaming cats outside. Not only to protect the bird population, but to protect themselves. They get in fights, they get hit by cars, get taken by coyotes, and they get diseases.

A catio is the perfect solution to having outdoor fresh, air bird watching and be safe.

I have two boys that were little feral kitten rescues, Gink and Griffon, and Brina is my little foster fail. They all love each other.

Before they had a catio they spent all their time in the window or at the French doors looking out at my patio and the birds.

I just feel good. I feel like I’m being a good cat mom. I’m really giving them a lot of input and stimulation and fun out here.

It makes me happy when I know that they’re happy!”
