Thanks krys. I have been putting off desexing him as he was a stray and we have since found out he is microchipped but the owners haven't contacted either the vets or myself (we left a message when he needed treatment). The vets seem to think that I can transfer ownership by going through the council but I'll have to phone them and see. I do have some citronella oil but I'm going to have to spray it all over my lounge room lol. He doesn't do it just in the one spot The vet did say though that even desexing him might not stop the spraying. Damn it - why adopt me lol
