Mojo has been in the house for one week now. He is 6 weeks old today. From moment one, Dusky, my 2 year old spayed female that I rescued from the park next door when she was about 6 months old, treated him like her own little kitten. Two weeks after I took her in, on the second vet visit for the booster and to talk about the spaying he told me that she was pregnant already. I made the painful decision to abort because the pregnancy was still early enough. I still feel guilty about it though. I'm wondering if Mojo's super easy introduction had anything to do with the fact that she was pregnant back then. Any ideas? Also, one thing I observed that left me astounded... when I first brought Mojo home, just a tiny 5 week old kitten, he would go straight to the litter box but would fail to cover his "business". I started to notice that Dusky would go to the litter box right after and cover Mojo's stuff. Yesterday and today I'm noticing that Mojo is successfully covering.
