Why is my new cat aggressive and peeing after meeting other cats?

Question

A has been with us for 3 years since 2 mths old, she's a lone cat, bad temper and doesn't play well. 3 mths ago, we brought 3 male kittens, B, C and D in. She didn't like them, hissing and trying to claw. We made a cat room and place the 3 in first since they weren't ok together. Their relationship is better now. Yesterday, we brought cat E. He's older than cat A. We put him in the room with B C D, day 1 was perfectly fine. Day 2 he's very aggressive and peeing everywhere, maybe he's in heat?

Oh my, that's a lot of cats, especially for a household that started with a cat who wanted to be an only cat. It sounds like cat E also would prefer to be an only cat. I would immediately separate E from both A and the B C D group. You have yourself 3 different fractions here and each needs their own space. I wish I could give you an answer that is more pleasing to hear. It's theoretically possible that cat E has some medical problem instead, but from your description, it very much sounds like a personality/behavior issue. The majority of cats would be stressed by this arrangement, unless you have happen to live in a very large mansion so they can spread out. It's just hard to integrate new cats in to households. Wishing you the very best of luck.
