my cat pees and poos in the toilet

So this crazy thing happened, my cat started peeing in the toilet

She always had litter issues and she has problems with cleanliness, before she peed in random places in my house

I took her to the veto who told me that it was probably due to stress

But recently she started urinating in the toilet, I was shocked because I never taught her that before, she did it by herself

Today I come home from work and I feed her, usually then a little poop follows

I see that she is heading to the FORBIDDEN rooms of the house where to poop, the dressing room and my bed, which obviously I refuse her by closing the doors because she likes to urinate and poop everywhere except in her litter box

But something crazy happened, she pooped in the toilet

Although this situation enchants me and I am shocked, I am still worried,

Do you think it’s due to stress?

I’ll send you a picture of her in the toilet

Thank you!
