Hey! So my 12 year old cat has always been great at using the litter box. But recently periodically she will squat around the room like she’s trying to poop and will squeeze out like one drop of poop, and then go to another part of the room and do it again. If I try to approach her she will scream at me. She will do this in like five minute intervals, and it usually ends with her going to the litter box and actually pooping. She has been doing this like once a week. Any way to help her and prevent this?
