My cat is two years old, and she has recently begun pooping next the litter box sometimes, and going inside the litter box other times. Is there a reason as to why she is doing this? The poop looks normal, and most of the time she goes inside the litter box and only sometimes goes outside it. And it is only poop. She is eating and drinking normally. Please help! I have no clue as to why she has started doing this. Thanks in advance for replies!
