Three days ago my boyfriend & I were in our yard picking up sticks from a recent storm and a tiny little kitten came running up to us. Over the past few weeks, a mother who gave birth to a litter of three has been occupying our yard so we have been feeding her, her 3 kittens and their dad. This kitten is not one of their clan. She is much younger and seems to be alone. After another 24 hours of her being in our yard and no mother in site, we decided to take her in. Currently I have her secluded in the bathroom. A crate lined with blankets is in there with her, in case she wants to hide. We've also included a shoe-box top as a litter tray. We bought KMR (kitten milk replacement) as well as some wet kitten food and she seems to enjoy both, although she runs to the KMR first. We did initially buy a nursing bottle but she seems to drink/eat fine out of the dish. We have only had her inside for about 24 hours, she has urinated once and had diarrhea about 4 times. She will crawl on us, come near us, play but she is obviously frightened and slightly skittish. When she escaped from the bathroom, I was easily able to catch her but now that she has escaped and seen that there is more than the bathroom, she will not stop trying to escape. I've read that it's better I keep her confined until she trusts us more. Based on my research I am guessing she's about 4-5 weeks old. I almost feel like I'm doing something wrong by keeping her because she seems so scared of me sometimes. We have a vet appointment set for next week. Any advice, suggestions or general comments would be greatly appreciated.
