Cat.containment.system. ......CAT! Well i wish them the best of luck with that. Mine would just run out the front door, or when quarantining a retired breeding queen maine coon we rehomed, she jumped out the fucking window. Second floor window.
No prison can hold a cat if it wants out badly enough.
Saw a van advertising something I've never seen before on way to work today; cat containment system for your garden using rollers on your fences!
