I was going to suggest citrus. Just know you have to repeat application regularly until they get out of the habit. Try finding other toys to keep your cat occupied. Sounds like they are acting out because they are bored. Maybe you can find some toys your cat would enjoy that are a little more self propelled (cause we all know how hard it is to find time to play with the cats around baby's birth).
Can you just hide the trash can under the sink?
@Alexus I didn’t even think of that! Smart but impractical. Maybe for a bit I’ll do that and then take it back out when the interest is gone. Thank you!
@Miriam sadly our cat is weird asf. She goes after onions and citrus! I tried the spraying of the trash can and it didn’t stop her. I put it in, on and around. She still went in the trash 😂 little bugger.
The cat is acting out because you are pregnant. It’s that simple. Trash cans with lids is the most fool proof solution. The other simple option is citrus. Cats hate the smell of citrus. Just know actually eating citrus fruit can make them sick. So it’s usually easiest to stick Orange peels or orange air freshener pods inside the trash can. Stick to citrus and avoid essential oils or onions. A lot of people suggest essential oils and onions and those can be deadly to a cat.
