my cat has recently started pooping on the floor in the same place for two weeks now. He has pooped in the same place 3 times. idk why he's doing it. Is he mad at me? can he tell something about my pregnancy? for awhile he was really affectionate and wanting to be around me all the time. occasionally I'm affectionate. I seem to just show my son more love and cuddles and not my husband or cat lately. Does anyone animals do this, and do you know why exactly?
