Dear Editor,

Do you own a large, young Russian Blue cat? He is male with a faint white mark on his chest.

If so, do you put him out at night in the belief that cats are nocturnal creatures that enjoy the darkness? Do you live in the Brookswood area, east of 208th Street and somewhere between 42nd and 50th Avenues?

If you should recognize this fellow's description, I have a confession to make: "our" or "your" cat now shares two homes. Most nights, Blue appears at our door and eagerly accepts both the canned and dry food we provide. He then settles down in his insulated box with mattress for a night's rest.

We have installed a cat door for his convenience, so that he can come and go as the mood takes him. We've taken him to a veterinarian to ensure he is unable to father kittens, and had his health checked. We now note that he is putting on a lot of weight due to the amount of food he eats.

We really want to know if Blue is ours or just a crafty opportunist who knows how to get what he wants.
