Advice needed please!
DS has just caught our male Dcat (7 months old) weeing in the bathroom sink. This is the second time we've seen him do this. For context he is one of two brothers. He was neutered a couple of weeks ago; his brother has not yet been neutered for medical reasons. We have plenty of litter trays that are cleaned regularly. No changes in his diet.
So why is he weeing in the sink?
And perhaps more importantly- how do I stop him weeing in the sink?!
