But need advice. Both cats sleep there at night, I lock them in so I can have a good nights sleep. ( If I don't then one cat will sctrach the carpet to be let out/ be fed at 3am and the other cat will decide she wants some loving and come pur in my face and bite my nose at 4am)
But, fistly my house stinks of pee and stuff. The smells carries through the kitchen and into the dining room. I've tried different cat litter, it doesn't make a difference. I change it daily. Also, the poo 'n' pee isn't necessary in the cat litter either 
Secondly, we're investing in a new conservatory roof for the sun roof and new doors, and would like to be able to use the room for us again 
So, how do I go about it?? Do I train them to sleep outdoors from now on? In the shed? I'm nervous that if I take away the cat litter (two trays) they will start peing in the house (again).
Heeelllp please???
