Good morning Jax, looks as though you have gotten an aweful lot of good advice already but I thought I would share my story with you as well. My husband and I found June Bug on July 3rd, I estimated she was about 5 or 6 weeks, her eyes were still blue and her ears were a little turned down yet like they had just opened. I was lucky enough not to work for the first week and stayed home with her for feedings and play time. We have 3 cats that are indoor/ outdoor and two that are outdoor. I kept her isolated from the older ones for the first couple of weeks to prevent a harsh meeting- I knew Scotch and Mike would not take kindly to ANOTHER kitten, and as I suspected Rocky, my youngest, took right to her. Kittens are clingy till they are about half grown, as it was mentioned in other posts by the fine people on this site, since she has no siblings and mother, you fill that roll. She needs one hundred percent attention until she is at least 6 months (or at least that is what she thinks!) As she matures she will be more independent. She may develop a focused personality however and when you are home she may just hang around you 24 seven. Rocky is like that, I cant be in any room without him being there too. However Scotch and Mikey only care if I am there to feed them lol! I find myself very lucky to have Rocky who is now a year old. He is still in ‘kitten’ mode and does alot of ‘babysitting’ for me as does the kitten who showed up in our tree row late last month. June Bug goes outside for about an hour at a time and plays with this kitten who we named Lucky. He is about twice as old as her so they really get along.
I have never heard that a cat reared without other cats being anything other than healthy, but then I have never experienced it first hand either as there are always cats around where I live! I agree with Raychela, enjoy your baby while you are the center of her universe, She will grow out of it and you will miss those days, and by the way, what a cutie!
