I'm pretty certain that it's one of my cars marking.
We got 2 new cats 2.5 years ago. One (which is now with exH) he didn't get on with and I think that's when the marking started. He gets on ok with the other, but hasn't stopped.
It's worse if I go away, but every day there's some. It can be on the kids toys, if I leave anything differ on the floor and there are a few common places. I was away for 3 days and I spent nearly 2 hours searching for and cleaning up wee this morning :(
I'm constantly paranoid that my house smells. I've tried the feliway stuff, but it's too expensive to use in large quantities.
I feel bad that he feels he has to do this, but am getting sick of the smell and clearing up.
Any ideas?
