Males mark their territory all of the time once they reach sexual maturity. Females scream, roll around, and pee everywhere when they are in heat (and can stay in heat for MONTHS). However, they do not bleed like female dogs:

2. Does a queen bleed when she's in heat, like dogs do?
No. A female cat does not bleed when she's in heat. If she bleeds shortly after a heat cycle it could mean she has a miscarriage. |
Of course, the biggest reason is so they don't reproduce needlessly when there are so many animals that need homes out there. My Step Daughters mom is the best example of what can happen if one does not take the time to responsibly alter their cats (this is long, but it to me is the perfect example):
Many years ago dH's Ex bought a female, Miracle, and bought a male, Shadow. Fortunately, she got him neutered right away. Unfortunately, she didn't bother spaying Miracle, and she got accidently lose outside and came back pregnant. She went on to have four: 3 females and one male. Ex's Mom took the male, DH (then later his dad) took one of the females. Since there were no intact males around, they didn't bother to spay the females. They were lucky when they didn't reproduce, and later they spayed those two and Miracle. Well, fast forward to just a couple of years ago. Ex took in two stray females Pandora and Sasha. She let Pandora come and go as she pleased for a while, and one day she came back pregnant. She went on to have 4: 2 males, 2 females (she later got back outside and never came back). We took one of the females and named her Isis (Shima was the other female). Brothers went on to mate with Sasha and Shima, producing between the two of them 8 kittens (1 died). DH and I took two of Shimas female kittens, Lily and Luna. They rehomed Miracles two remaining kittens and one other female kitten, and neutered the two brothers, but didn't bother doing the same for the last remaining male kitten they had. Well, DH and I had a feeling this situation was going to get even worse than it already was, but we had no idea how bad. We offered to pay for the male kitten to be neutered since they had four females capable of reproducing. They said no. A couple months later, Hailey tells us that Sable (the male kitten) started marking, and that the females were going into heat. We decided to take Shima out of there since they didn't want her, and we already had her sister and two daughters at home. We hoped we stopped her from getting pregnant, and Ex insisted it was impossible that she was pregnant. I took her into the vet, and sure enough she was, and later she ended up having four beautiful kittens. The three remaining females? Two had litters (total of 8, 2 of which died), with the third, Sasha, about to pop any day. So, if I did my math correctly, here are the totals, and they speak volumes:
The total that has been through that house in one form or another is 32.
Of those, only 4 were intentionally brought into the house.
That means that over 28 lives could of been prevented. Who knows what that total will be once Sasha has her kittens.
The moral of the story - unless you are a good breeder (one who does it for the love of the bred instead of money)reproducing quality animals to improve their bred, spay or neuter your pets!
