We have just rehomed two rescue cats who were rehomed together as they would not be separated. Female is shy, but no concerns. Male (neutered) has urinated on the hall carpet yesterday, and again today, despite using the (scrupulously clean) litter trays for the best part of a week. Any tips on how to stop this behaviour?
I am assuming it will help when we can let him out, but will go made if I end up scrubbing stinky wee out of my carpet every day until then.
