It’s for cats too! Kittenmitten is an indoor cat  has hated the outside ever since he was a kitten. I tried all types of carriers and nothing worked. He would panic and get anxious.  I decided to try the stroller so I could exercise as well by walking him.  Let me tell you he’s a different cat. Absolutely loves the stroller because he has room to move around and he can see everything. This is one of the best purchases I have made in a long time.
