They may be ill and/or abandoned but can see no reason not to relax and take advantage of the amenities. Food, a warm bed and whatever else they can get.
I got a bed, heat pad, food water. I managed to remove that annoying catheter from my leg. Now quit disturbing me human.
No mum but not worried food still on tap and it is snuggly.
Look human l am not going back in there now go away and let me eat in peace.
I will just wait here for the next snack to arrive zzzzzzzzzz..........
Me n Teddy going to take on the world, he is my new friend since l was abandoned.
