Why Is My Chinchilla Peeing Outside the Litter Box?

Chinchillas may urinate in the wrong places for several reasons—bad habits, low mood, estrus, territorial marking, or an underlying urinary infection. Each cause needs a different response. The key first step is to clean any accident thoroughly so the scent doesn't train your pet to reuse the spot. Feeding on a fixed schedule keeps a hungry or unhappy chinchilla calm, while separating cages and considering neutering curbs marking during heat. If urination becomes frequent or the urine looks dark, a vet check rules out infection.
