There is a gorgeous black and white cat which recently we see most evenings in our garden but I think he may be a stray. He is fairly long-haired, looks quite young and fit but his fur not great - sometimes he comes right up to our patio doors and looks in. Obviously I need to find out if he is a stray and I guess a paper collar is the best way but he is wary if appoached. Is it best to leave out food for him to gradually gain his trust ? Any other suggestion please ? A few months ago another cat who I thought belonged to a neighbour turned out to be an unneutered stray who we took to the vets but had to be pts following a serious road injury - just want to do all I can to make sure this little one is safe as possible.
