My neighbours have two male cats, both neutered. About 16 months ago, they had a baby and since then the cats have pretty much been left to their own devices. They are not allowed in their house, and nothing has been arranged in regards where these cats go and sleep. They leave some dry food outside in a bowl, but thats about it. They are very rarely at home. When we had the last lot of snow (nov 2010) both cats moved into my garden,, as i provide shelter for mine for when they are outside. Over the summer when i had my doors and windows, both cats pretty much moved into my house. My neighbours are aware of this. A few days ago, i noticed the smaller of the two sneezing constantly. I informed my neighbours, but they have done nothing. I know this because he hasnt left my house. I do know he is vaccinated up to date. There is no discharge from eyes or nose, but he is very subdued and down in the dumps. He is eating. Can i legally take him to the vets myself? As he pretty much lives under my roof, i feel responsible for him, and he certainly needs medical treatment.
