No problem! Unfortunately one of them did develop a change in behavior, but I wouldn't put it down to the cattery. We opted to put them both in one pen; I was worried that if I put them in separate ones, they'd get used to being apart and then not want to be around each other, and that if I put them in the same one, they'd get sick of each other. So I felt like I would be screwed either way. Now, where they used to rarely fight, and they'd even curl around each other for a nap, the one growls, hisses, swipes at the other one if she even passes her. They fight a lot more now. This has been since the beginning of December, but very recently they're starting to sometimes be on the bed together. But again, I wouldn't put that down to the cattery itself.
