My girlfriend is having issues with one of her cats. The cat will leap off the litter tray before finishing going to the toilet trailing poo behind it and sometimes scoots herself along the floor to clean herself. She wees in the tray no problem and has used the tray in the past with no issue and also goes outside but due to recent cold weather has stayed inside. There are 2 other cats in the house that have lived together for years and there a multiple trays in the house that are kept clean. As well as this issue with the tray she has starting running away after she eats like she is being chased which is also new. There have been no changes round the house, and litter and food has remained the same. Any idea what has caused this strange behaviour.
