How can i get rid of stray cats who keeps coming in our apartment window.?

Is there any repellant that i can use without harming the stray cats? i do have a dog inside the house that usually doesnt finish his food so most of the time the cats would smell the lefover food and try to sneak in to get a piece of whats left. Hope you can help me. thanks!Got some interesting answers, thanks! though i need more suggestions. we usually leave the balcony window open for our dog to poo and pee outside. so we really cant close the window, darn cats!Hey thanks for all your suggestions. will try some of it and see which one works well. hopefully they'll just stay away from our balcony window coz im afraid our dog might get some unwanted disease or virus from these stray cats who just loves to check our dog's dish. Thanks again!

shut the window

well, u can kick them, it probly doesnt hurt that much

you can get a bitter apple spray and put that on the window sill, or you could just get a spray bottle, fill it with water, and everytime the attempt to come into the window, spray them, they'll take off real quick.

try using pepper, spread along the window sill cats hate it

Keep the window closed. Whenever the dog doesn't finish his food, put away the extra food immediately and wash the bowls so that the cats won't smell it.

Invite Indonesians over for dinner, and cook some native foods of indonesia, one which includes.....

put a dash of seasoning spice on the leftover, the cats will start sneezing

close the window or start adopting cats.or move.

you can buy expandable window screens at any hardware store & insert it in the window

Put a screen on the window.

here's a little trick i learned from my mum. put orange peels on the window it seems like cats don't like it's smell. i tried it and it works quite well. other wise get a dog there you'll be sure that no cats will come.

use orange, lime or lemon peels and slices around the window, cats HATE that smell!

Someone once told me cats do not like the smell of moth balls. Maybe set them around the dogs dish or around the perimeter of the patio for a few days or weeks. It can't hurt to at least try it.

you got to let the cat know this is your territory by frightening them off. You don't have to hurt them just let them know in no uncertain terms that a bigger scarier cat (ie you) lives there! Be really aggressive without being violent.

I have found that the most simple is the most effective. I spray Citronella oil around my house to stop stray cats they cant stand the smell but beware if ur cat is an outside cat it may not want to come back.

Call your local animal control and tell them you have cats that are a nusiance to you and they will most likely bring a cage out.when you catch one , get it in the cage and call animal control to take it away.
