Will my cat learn if i hit it?

Brief：
it snuck downstairs into my room no no. You need to do that consistantly so that they will learn that its not good and no no means stop. Hitting it wi.. 

it snuck downstairs into my room & knocked a plate of food over & dovoured it on the carpet, if I show her the plate, then whack her with a stick, will she learn to stay out my room?

if not, how do you teach cats?

No, that will not teach her to stay out of your room. All she'll see is some large person brandishing a plate and beating her with a stick..she won't connect one with the other.

Spray bottles (water) and loud noises help deter cats. If you want your cat to stay out of your room, make a loud noise every time she comes in. You can put marbles in a metal jar and shake it every time she tries to come down. Or spray her with water when it happens. But NEVER hit a cat..it will only breed resentment in the cat and possibly make her mean. No animal learns anything but distrust from abuse. Cats hate water, use a squirtgun to correct bad behavior (not a blaster, a squirt bottle or regular squirtgun). Dogs are better. GET A WATERPISTOL AND SQUIRT THE CAT WITH WATER WHEN IT DOES SOMETHING LIKE THAT yes beat it. that's how they learn..burn it once in awhile. pets never learn well with negative stimulus not directly associated with the event. If you can catch it in the act and spritz it with a squirt gun, that can help extinguish the behavior. Showing the plate doesnt associate the act with the consequence, it's too late. Never hit pets, they then associate you with hitting. No, that is animal abuse and animal cruelty! If you hit her she will learn to hate you and then you will have a bigger problem on your hands.
