Pet's info: Cat | Mixed Breed | Male | unneutered | 5 years and 6 months old | 10 lbs
We have a 5 yr old male cat, not fixed, some yellow stool, recently strong ammonia smell from litter box no weight loss, he's generally moody anyway, so hard to tell about behavior change.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! The strong ammonia smell is likely due to the urine being concentrated (not diluted by water intake). Male cat urine also has a special "scent" for marking. Neutering will help with this. The yellow stool will require a fecal from your veterinarian to check for parasites. Hope this helps!
