Long story follows, TLDR at the end:
My indoor cat got out a couple weeks ago and came back after 12 days. To get him back I put out mountains of food each night and covered the yard with motion sensitive cameras and started leaving the door open anytime we were awake. We caught him on camera each night along with at least 10 other cats, along with skunks, raccoons, and possums. One morning I came out from my office to refill my coffee and a strange white cat was inside my kitchen and bolted. We eventually caught our cat on camera when we were awake and called and he just walked through the door a half hour later.
After we stopped putting food out our yard ceased to be the cat hangout, except for that white cat. This cat was out at the edge of my yard and started meowing loudly every time he saw me or my wife. We felt guilty and started bringing him food, of which he eats massive amounts. Over the days he’s gotten more friendly and I finally picked him up and petted him. Now he hangs out in my yard a good portion of the day, and he hears me getting up in the morning and is howling outside my door.
He’s declawed, and deceptively light because he has a very thick coat and long fur. He’s got burrs matted into his fur, but that isn’t really uncommon for an outdoor longhair. He’s been eating 1.5-2 cups of cat food each day for a week, which is double what the bag says an adult cat needs a day. So I really doubt he’s eating anywhere else.
So, to my question, how do I figure out if he’s owned? While my cat was gone we plastered the neighborhood with flyers, most of which were ripped down. Some jerk called and said we were idiots for offering a $100 reward for a cat, saying “It’s not like it’s a dog”. So I’m not enthusiastic about putting up more flyers. I put an ad on craigslist, but I’m not hopeful about that.
TL;DR:
Have a cat hanging around my house, trying to get in. Seems skinny, is declawed, matted up fur, definitely not feral. Eats twice what a cat normally needs, and is always begging for food loudly. Crummy neighbors and neighborhood rule out any kind of door-to-door search for owners or flyer campaign.
We kind of want to take him in, but we don’t want to steal someone’s pet. Ideas?
