I recently switched brands of litter and now my cat wont use the litter box. Why did this happen?
Cats are creatures of habit and if you force an abrupt change on them youll run into trouble. If you must switch brands of litter, do it gradually by mixing a little of the new litter in with the old brand. Over the course of 5-7 days you can increase the amount of new litter and decrease the old. During this time, monitor the box carefully to make sure your cat is handling the transition successfully.
