Why would a cat's nose bleed after death from heart failure?

Thank you for using Petco Pet Education Center, formerly Petcoach! An elevated respiratory rate can be caused by heart disease or lung disease and can be an indication of difficulty breathing. High blood pressure can be secondary to heart disease and occasionally thyroid issues, both of which can be controlled with medications. I recommend having Molly seen by her vet as soon as possible, as this can progress quickly to pulmonary edema and even heart failure. She may need to be seen by a veterinary cardiologist for a second opinion and titration of medications.

I am very sorry you lost your cats! That is terrible. Unfortunately the only way to find out what killed your kitties is to have a post mortem done. There are so many possible causes, starting with household cleaners, insecticides, rodenticide, snake bites, toxins, and also infectious disease. From these signs alone it is not possible to say what could be the cause. Again, I am very sorry.

I am so sorry you lost Buffy! I think it’s unlikely that the heater was the cause of death - I would think you would see some kind of burn or hair loss externally if that was the case. Heart disease is one of the more common causes of sudden death in cats and can cause bloody fluid to quickly build up in the lungs and come out of the nose and mouth. Other possibilities would be kidney disease, blunt trauma or a clotting disorder. You could ask your vet about a necropsy (autopsy) which might reveal a cause of death.

Cats in heart failure don't generally cough. Unfortunately, it can be very difficult to detect heart disease in cats until they are already advanced without regular veterinary visits. https://www.petcoach.co/cat/condition/cardiac-disease-1/ The most common cause of sneezing is a viral infection but allergies, sinus abnormalities, other types of infection and cancer can also cause sneezing. I recommend to play it safe and have your kitty examined. This is the best way to determine the underlying cause. I hope this helps and please feel free to post any additional questions.

Hi, I am sorry to hear that Mary passed away so suddenly. It must have been a real shock for you. I think the fluid you noticed is inflammatory fluid coming from the chest because of the presence of cancer. This is secondary to the presence of the tumour, sadly can’t be treated and does aggravate the breathing itself. I hope Mary did not suffer. Thinking about you at this difficult time.

Oh my goodness, I am so sorry to hear this! I would be concerned that Maya either got into something toxic while she was out running around or she became overheated and died of heat stroke. There is also a chance she could have had an underlying heart condition that was never diagnosed. Finally there could have been some sort of trauma she encounter like being hit by a car. The watery blood that came out of her nose has most likely come from her lungs. This can be abnormal finding after an animal passes away under more traumatic circumstances. If this recently happened you could take Mays's remains in to your vet and request a necropsy be performed. This may help determine her cause of death. Much sympathy to you.

Poor Eli! Severe dental disease can certainly cause nosebleeds and nasal discharge, since the roots of some of the upper teeth are connected to the nasal cavity. It's also possible that he has a severe bacterial or fungal infection, a foreign body of some kind stuck in his nose, or even a nasal tumor. I would recommend taking him to the vet as soon as possible to have this checked - he/she can do a thorough oral exam under sedation if needed to help determine the problem and see what needs to be done to treat it.
