Laili, at 7 months of age, the females are likely to start coming on heat. Please be sure to keep them separated from the males, or you'll find yourself with litters of kittens in the next few months. Also, this cage is very small for so many cats -- perhaps you put them into it just to photograph them? I hope they don't all spend much time in that small space! Best of luck finding adopters quickly.
yeah..i pity them also...but there's nothing we can do..i live in an apartment and can't get bigger room for them...thats why we are trying to find adopters as soon as possible...thanks for the advice anyway.. :)
