Tabby kittens & cats in Kenton, Ohio

This kitty showed up in our yard ~10 days ago, got into yowling contests with our feral male Siamese named Simon. We did not want another feral but thought Simon might like company; however, within the past few days the stray has become very aggressive toward Simon and chased him away. I moved the stray into our 3-season room with a radiator, so he/she (gender unknown) has been warm and has eaten all food provided (very hungry), but our house is tiny; Simon still sees the stray and only stays long enough to grab some food. The stray is otherwise friendly, walked into the house and does not mind being picked up/held, likes belly rubs, etc. and purrs quite a bit. Seems very much like a former indoor cat that either wandered off or was dumped. I took to the vets to scan for a chip (negative) but otherwise have not had any health checks done and again gender is unknown. Seems like a good potential only cat, or maybe with other cats (seems to like our pup too) in the right situation.

I marked Unknown for Good with cats because Paddington gets along well with our male tabby (in one of the photos), but she attacks our shy tortoiseshell. We tried to get them to at least tolerate each other (Feliway, calming powder, scent transfer, etc.), but the problem has actually gotten worse. She found our yard as a tiny kitten, maybe 6-8 weeks old, last summer (2024); we had two feral cats and she started eating their food. We caught her and took her in; and as noted in the description is spayed and up to date on all of her shots. She enjoys pets, cuddling, and being held/carried - plus playing with my shoelaces - and can play hard w/our male tabby and our terrier puppy (though the puppy chases her quite a bit) - but everything changes whenever Paddington sees our tortie. We think she would be ideal as an only cat, or maybe in a house with a confident, playful male and/or a dog. We hate to lose her, but she is in a large multi-level kennel much of the day and is not fair to her.
