We have been feeding a kitty that showed up on our porch. We think it's a girl but not sure. We're calling her Little Kitty. She has a knicked ear, we think she's been taken to the vet, fixed and released. But what is weird is that she's socialized, not completely ferel. You can pet her, and brush her. She loves attention. She'll roll around on the porch so you can pet her. But we have 2 cats inside our house, and our cats have lots of windows to look out of for entertainment, and Little Kitty on the porch hates our cats. Little Kitty jumps at the windows and hits her paws hard against the glass towards our cats. Little Kitty hits hard on the glass, it's loud. Our cats hiss back at her. So I don't know what we're going to do with her. Keep feeding her of course. We gave her worming medicine, because I thought her tummy seemed too hard. And we put Advantage flea meds on her. Our 2 indoor cats are so spoiled and relaxed, I wonder if interacting with Little Kitty on the porch is traumatic or is it "interesting" to our cats, excitement? Is it good or bad? I hope this isn't stressing our cats out.
