I receive more questions about solving common litter box problems than any other cat behavior complaint. Young kittens won’t automatically know where to “go” and you’ll need to teach them potty etiquette. Adult cats understand the basics, but can get their tails in a twist over a variety of issues. Health challenges prompt cats to find alternatives to the legal toilet, and even after veterinary diagnosis and treatment, owners need to address the behavioral aspect to solve litter box problems.
