Why is my senior cat wheezing, drinking lots, and has fishy breath?

Pet's info: Cat | Domestic Shorthair | Female | spayed | 9 years and 10 months old | 17 lbs

Our cat Jake is almost ten years old. For years he’s been overweight and is obsessed with water. Whenever he breathes, his sinuses sound clogged and he weezes. His breathe also has a very foul fish odor.

It sounds like there are a few things going on with Jake healthwise at the moment. The wheezes when he breathes could be due to a respiratory infection or heart disease. As for his bad breath, that could be caused by dental or gum disease, abnormalities in the mouth, respiratory system, gastrointestinal tract, liver or kidneys. Some of these causes can be very serious, so I recommend giving your vet a call a first thing in the morning to get an appointment for him asap. Best of luck, I hope this helps!
