Me and my roommate went to an Adoption Center and got a 7-8 week old kitten. About a month later, we got 2 new cats. One was about 9-10 weeks old ,the other a little 6 week old. Well after a week or so the cats got use to one another. They no longer hiss at each other or run away. Well I have had cats before when I lived with my parents, we had 3 and I remeber they would always sleep together in one big circle. Now Eclispe (10 week old Female) and Tiger (6 Week old Male)will lay with each other, but Buffy (Our orignal cat, 9 Week old, Female) will not lay with them. In the bed Eclipse and Tiger are balled up together on one side and Buffy is on the other. Just yesterday I was on the couch and Tiger and Eclispe were laying with each other but Buffy went into the window seal to sleep. Do cats always sleep with each other? Does Buffy resent them?
