I adopted two 9 week old kittens(close siblings), plus I have an older cat in the house. Initially, everything went fine with both using the litterbox. One is still doing so, however the other has stopped and has been pooping on the carpet in various spots for a few days now. I have 3 litter boxes(at least one for kitten only) in case the one kitten is touchy about sharing. She is pretty bold in most other ways and is not showing any fear of me or the new environment.
Any suggestions?
