I have two indoor cats, have had them for six years now.
In the past couple of weeks, on of then has taken to peeing outside of all the litter trays (we have four large ones around the house). He's never done it before, he does it right beside all of them. Nowhere else, just right beside them.
I took him to the vet last week to see if he had an infection (he did it once years ago when he had cystitis) but he was given the all clear.
Litter trays are emptied of feceas as soon I see they have been and are totally cleaned out very regulary.
We moved to this rented property about a year ago and LL doesnt k ow we have cats. I don't know what to do, but it's starting to smell.
