Right, an update on the "door" for the litter tray ......
I put Polly in the tray and popped the door on. It took her a few minutes, but she managed to get out in the end
. Whereas Fergus I put in, put the door on and he just sat there as if to say "ok, I'm stuck in here now, I'll just sit and wait, it's fine"
!!! After a while he started sticking his paws out the bottom of the flap, then Polly started to jab him back so they had a good 5 mins playing like that, but he has eventually worked out he can get out on his own.
