Ok..as many of you know, I am a teacher. One of our kids at school (ADAM) has a cat (HARRY). Adam and family adopted Harry a few months ago from the local shelter. They had seen Harry on a story on TV- Harry's previous owner had him declawed. The vet messed it up and they had to amputate Harry's leg. ADAM ADOPTED HARRY THIS WAY!!!!! At any rate, Harry does not always use the litter box. The family has a 15 yr. old cat that gets along w/Harry fine. Harry has no difficulty getting around. The household has 2 litter boxes- though both cats have access to both. Adam's mom says that Harry will use the box for 2-3 days, then urinated next to it on day 4. Any advice? Mom seems certain that the kitty doesn't have any UTI problems. They clean the boxes daily too...thanks in advance. Adam is very stressed, doesn't want to have to get rid of Harry...
