Urinating around the house

From: Kevin with cat Mr. Wu
Breed: Unknown. Looks part Siamese.

Pet Symptoms:
We have taken in a stray male cat. He is ”Complete”. We have four other cats, all strays. Our new arrival seems settled, happy and is friendly. Unfortunately, he has taken to urinating around the house. We have litter trays and have tried to encourage him to use these – which he occasionally
will. Have you any suggestions as to how we might stop this behaviour?

Further Details on your Pets symptoms:

No symptoms other than he seems contented, eats well, shows no aggression.

Showing him the litter trays – usually too late

Our Advice:
I would advise you to castrate him ASAP. You can use Feliway as well.
