I feed cats, too, that's why they show up at my house. I cannot turn my back on them. For some of them, I am their lifeline. I take that responsibility seriously.
Do you just feed them or do you provide medical care (shots, etc) and spaying/neutering? If neither are provided the cats will gets sick and just continue to reproduce (and they inbreed with strange looking off-spring). Rabies are always a concern for non-vaccinated cats.
No, it is good you are finding homes for the kittens. Even taking them to the SPCA is okay, because they're just kittens and easier to bring around than a full-grown feral cat.
Both our dogs and our cat are from the spca. I wouldn't get a pet from anywhere else -- well, if we found a dog or cat we'd keep them if we could. It took over a month for us to find our first dog and our second dog was literally we were in the right place at the right time. Great pets all of them. Yeah, even the cat who marks! lol
Yeah, the marking is not acceptable to me. That will be Lazarus's true test. If he marks in my house, he cannot stay. I have my limits. I will cross that bridge when I come to it. My husband and I are talking about putting a cat door leading into a pen in the garage, so at least cats could come in and sleep in a warm place. We shall see.
Our cat, who is neutered since 4 months old, started marking randomly when our first dog was about 5 years old. Since he was marking on her dog bed and sofa it was next too, we assumed he was marking his territory because her bed was where it was. What we didn't know at the time was that cats were wandering around our house and our windows where the dog's bed/sofa are were open much of the time. One night we heard cat screaming and the window screen was ripped all the way down. Apparently a cat was outside while my cat was sitting on the sill inside and they tried to get each other. That's when the light bulb went off about his marking.
We had a mom cat who had a litter of 6 kittens under our front step on Mother's Day. Our cat started marking the damn living room curtains when they showed up wouldn't stop (I took all the curtains down I was tired of washing them) for quite some time, despite that the mother cat moved those 5 day old kittens the night we found them.
I use a product called Simple Solution to clean up any marking. It's enzyme based and removes the odor/stain completely. I tried many products before I found this. Oh, and did you know that female cats can also mark? I didn't until I saw a female marking my neighbor's property!
If the kittens you found are 5-6 weeks and you trap the mom, you might be able to get the kittens by hand. They aren't too fast just yet. Don't be afraid if they hiss and growl, they're just scared and they won't try to bite you as their teeth are too small. The ones we found ... their eyes were still blue and just changed to blue/gray the last several days.
