Spick, it's not safe to let cats out everywhere - when you're in the middle of a large city e.g. (Cologne in my case)
I suppose your right there Kiya, but in my case it's just fine my garden is the size of of a footie pitch, all grass, several trees and a wonderful Privett hedge.
Should people really have pets that need space and the great outdoors,if they live in a confined space or inner city?
