My cats kept looking at e as they sat in their own beds until I gave in on tuesday and lit gas fire.  They haven't been outside at all since then as I had the litter trays down for them.  I've fooled them this morning and have removed them.  I bet they don't take log out there to do what a cat's gotta do.... (when there's no litter tray!)
Can anyone tell me why, with 2 litter trays available to use, do they take it in turns, forming an orderly queue, to use the same one?
The cat here looks exactly like my Rojo.
