how do i keep stray 猫 especily tom 猫 in heat away from my female 猫 that stay outside?

Are your female 猫 spayed ?

There are 2 ways:
1. Get a dog which gets along with your cats, but hates tomcats;

2. Keep them in the garage, litter box train them, leave the windows 或者 the door open for a little while, but watch over them so they don't run away.

Those are the solutions which could work, if they don't 你 can always spray the tom 猫 with a hose. However, if your 猫 are spayed maybe (just maybe) the tomcats will leave them alone. Hope that helps.

i guess a very slick fence?

I would bring her inside, if she is not spayed. If 你 don't 你 will most defiantly without a doubt end up with kittens. I would spay her too, it's a good thing to do if 你 continue to keep your cat outside. If not she will continue to breed with male 猫 and adding to the already over populated cat problem.

Spay them, and don't try to look for someone else to pay for the spaying that's just being cheap.

there really isn't a way. The cat has to be away from the females 或者 fixed.

Lol, good luck with that, try throwing a boot at them. But unless 你 actually do something about the toms themselves like catching them and sending them off to a shelter 或者 something there really isn't much 你 can do about it. Even if 你 kept them in the house the toms would still come around. I personally don't like the shelter idea because to me that just sounds plain cruel, know if they get sent to a shelter a stray will most likely just get put to sleep. My brother works at an animal shelter a really big one and he says all he pretty much does is kill stray 猫 and 狗 all day:(

Just get 你 girl's spayed, and if they already are well don't know what else to say.

If 你 keep your 猫 outside and they are not spayed they WILL get pregnant and have 小猫 without fail. Don't be surprised if they are already, it doesn't take much. I know I've had a LOT of cats. Also if 你 keep your 猫 outside they are very likely to run away, 或者 get hurt, find bad food, 或者 get sick. Stray toms can be rough and cruel and if your 猫 aren't tough enough they just end up getting bullied if they don't cooperate with the courting male that comes around calling.

If 你 don't want 小猫 get them spayed!

If 你 don't want Tom's Attention spay them and keep them inside! It will minimize the toms' attention, but it won't eliminate it.

*Locking them in the 车库 with the window open won't work, because the toms will get in, and eliminates the point. Even if there's screen they will tear it open, never underestimate the strength and determination of a cat in heat, 或者 a male who senses a cat in heat.

或者 like Yoki69 说 try getting a dog who will guard your cats, some 狗 will do that if they're territorial enough and get along with your cats. But no promises.

If 你 live in Nova Scotia, Canada, The Spca Will spayed your 猫 for about 140 dollars and I suggest 你 do. I have 2 female 猫 that where not spayed but never went outside and i still got a bunch of toms outside, the cat population in my neighborhood is really high and people like 小猫 but they don't care for adult 猫 very much, try 蛾 balls and pepper on your porch.
