Are medications for my cat's enlarged heart and lung fluid safe?

Updated On September 23rd, 2025

Pet's info: Cat | Bombay | Female | spayed | 5 years and 5 months old | 8 lbs

Hello! my cat was diagnosed with an enlarged heart and fluid in her lungs yesterday. After running countless tests that came back negative for the cause (costing 1,300 for no answers mind you), our vet gave us a combination of furosemide 12.5 mg twice a day, enroflaxin 22.7mg, and 1/4 of 81mg buffered aspirin. After doing our own research we found out all of these drugs interact and were told they could kill our cat by the vet. We are just looking for a second opinion if these are safe for her.

Hello, sorry to hear about Meef. It sounds like she may be in congestive heart failure and thats why your veterinarian gave you those medications. The aspirin and furosemide may interact with one delay the excretion of these medications from the body. This can make the side effects of the medications most likely to occur. The biggest one we worry about is damage to her kidneys. If I were to pick one medication over another, I would give the furosemide as that will get her out of congestive heart failure, however the aspirin is also necessary. There are other medications that your can talk to your veterinarian about such as clopidogrel which will have the same effect as aspirin on the platelets and will not interact with furosemide. Ideally, depending on how severe her signs may be, Meef should be hospitalize to monitor her heart condition and fluids in her lungs. Monitor her respiratory rate. If you notice her breathing to be fast or labored, or if she has open mouthed breathing, you should bring Meef to the emergency clinic immediately. Hope this helps and best of luck.
