We used to have 3 trays but they ignored two and all prefer the one massive one, so now I have the one, cleaned daily as Portia at 16 hasn't been out all winter, and the other two use it in the night, or if there is a drop of rain outside!
We use very fine clumping litter and like it, but it leaves a kind of pinkish dust film where they walk (and they scuff it everywhere). Currently it resides in the downstairs loo, but DS2 (who has ASD and coordination problems) tends to trip over it a lot! I don't want it in the kitchen, and we don't have a utility room.
I refresh it (scoop) before work each morning and then again/clean in the evening but often when I get home from work the first thing I notice is cat tray smell.
Any suggestions how I can make it less stinky? Ideally I'd like them to go OUT but they are stubborn!
