Isn't it interesting the way male and female cats behave regarding new additions, not their own kittens. Grasshopper (female) will not let another cat live with us (we've tried!) However, years ago I had a cat that had a litter of six. One day I went into the room where the kittens were kept, and there was Meatball, my neutered male Siamese, curled up in the kitty bed with all six kittens "nursing" on him! He was giving Aqualung a break, she was pretty tired at the time. Aphrodite, the other female (we thought Aqualung was a male when we got them!), wouldn't have anything to do with them!!!!
WTG, Noah!! I am sure when Basil gets a little bigger Noel will develop a tolerance, if not a love. Maybe she's jealous of Noah's new found "baby"?
