I just got my 8 month old cat spayed 5 days ago. And I just went to check on my cat & I found the most disgusting thing ever in her litter box. Its a long poop shaped reddish light brown piece of tangled hair. Its not poop mixed with hair.. JUST HAIR. She seems healthy, eating normally & playing. what is this??? I noticed that she was licking the gauze that was covering her operation.. could it be that? or do you think its serious?
