What's wrong with my cat?

It's not uncommon for cats to develop a habit of licking various surfaces for no apparent reason. One suggestion i read is that it's boredom or stress but, in most cases, I would doubt that. Cats can become addicted to tastes and textures and it could be something like this but usually there's a very good reason why they develop this behaviour in the first place. It's possible that there are salts in the paint or plaster which she is licking off. Most bricks and plaster have some salt in them which comes to the surface when water in the masonry dries out. It's unlikely to do her much harm. She's either developed a taste for salt or she actually needs it in her diet. It may be a good idea to take her to the vet so that she can be checked for iron or other mineral deficiency.

I don't have any idea what is happening to your cat..

idk but my dog keeps trying to lick my belly button. Maybe time to see the vet

@Ken1rt Maybe that is something the cat picked up.

I think it is quite normal for cats to develop this kind of habit, maybe sensory stimulus like smell, texture or taste might be good or it may have become a game out of boredom.

Having tantrums coz she's hungry

I just saw a video of a dog who constantly licks things: the floor, the walls, and even people's feet. They determined the dog is just flat out weird. But just in case, I would ask the vet.

May be she is liking the taste or smell of the paint on the wall

Nerves. My dog was nervous and she did that a lot.

My niece used to do this when she was three. She said she liked the taste of paint.

I don't know why your cat did that but to be sure take her to vet if it continues. Don't think it's something alarming tho.

I think your cat likes the coolness taste of the wall

It means you have a strange cat ??
