How can I prevent my cat from eating my mashed potatoes?

If your cat keeps eating your mash potatoes, and you know they are covered in butter, milk, cheese, and much more, you may be keen to learn how you can stop it from happening. Here are some suggestions.

01. Keep your food refrigerated when not in use

If you tend to leave some of your meals out on the surfaces at night, or while you relax you will need to change this habit. Basically, refrigerate any uneaten mashed potatoes so your cat can’t get to the scraps.

It may take some discipline, but it will be worth it, who wants their cat in their leftovers anyway, right?

02. Close your kitchen door when eating or cooking

If your cat is stealing the mashed potatoes while you are trying to eat, or while you cook, try closing the room door to stop it. It is likely to make noise and meow outside the door, this is normal.

But, in time, it will learn that this  is a no-go zone.

03. Place kitchen foil around the countertops.

Another trick is to place some kitchen foil on the counter tops. Most cats do not like this material and it can help to train them to stay off the counters and stop grabbing your mashed potatoes.
