Hey Zhann, the "kitty run" that your hubby built for your feline companions intrigues me. Ever since my cat Gracie disappeared I've kept my other two cats in the house. I hate it that they can't go outside currently,but I've lost two beloved cats in two years and I'll be damned if I let these two become coyote chow. My question is, how big is the enclosure your hubby built, and do your cats seem satisfied with being fenced in? Thanks!
