Quite often, heart disease is diagnosed in ferrets that are 3 years old and over.

Dilated Cardiomyopathy causes thinning of the heart walls and the heart will then overflow with blood. The thin walls are therefore not strong enough to pump the blood out to the rest of the body.

Hypertrophic Cardiomyopathy causes thickening of the heart walls, thereby reducing the space in the middle of the heart. Due to the decreased space available, less blood is able to enter the heart so as the muscle contracts, only a small amount of blood is pumped out.

Some of the symptoms of cardiac disease are

Weight loss
Swollen abdomen
Breathing problems
Tired after playing
Increased respiratory rate
Weakness, especially in the rear legs

Your vet will most probably give your ferret a diuretic to get rid of the fluid which has built up in its body, and probably other medication to help the heart.



In July 2007, my oldest ferret, Kaos, was diagnosed with dilated cardiomyopathy.

Unfortunately my brave little girl lost her fight on January 28, 2008.

Cardiomyopathy & Heart Disease in Ferrets — 2 Comments

  1. I had a question? I recently adopted 2 ferrets. Not sure about there age or health.the people who I adopted them from didn’t take very good care of them. One of them was balding in one spot on his lower back and the other one had a scab on his ear and looks deformed a bit. But my question is, I’ve found blood on my walls in my room where they run around. It looks like as if something had sneezed blood on my wall. Could this be the ferrets? Is it possible that they could sneeze or get blood on my walls or do you know of any diseases that would cause that to happen? I’m wanting to take them to get vetted but I am saving money for that. I just thought I would ask and see what could be happening and if my ferrets are okay? Thanks (:

  2. Hi Natasha
    Oh gosh, your poor little adoptees :( So glad you rescued them but it does make me angry to hear about how previous owners mistreated their animals
    You said one ferret had a bald spot on his lower back … that *could* be due to adrenal problems or the hair loss *could* be because of stress caused by what happened with his past life. Only a vet can tell you what the problem is :(
    Re the scab … that could be because your ferret has ear mites and, if the poor thing was neglected, his nails might have been long and when he scratched his ear, he might have caused the scab. I also have heard that bored ferrets will scratch themselves more so that might be the cause too! I honestly don’t know :(
    Re the spray of blood on your walls … oh Natasha, I also have no idea what could be the cause of that. I googled the question and found this information on PetMD …

    I hope you’ll be able to figure out what the problem is for your ferret and I really, really hope your vet will be able to help them if they’re sick! I trust you have a ferret vet?
    Is it not possible for you to get something like CareCredit where you can take your ferret/s to the vet and pay the bill off in instalments?
    I do worry about the fact that IF it is one of your ferrets sneezing blood then he really needs to see a vet ASAP!
    I really wish I could give you some idea of what *might* be wrong with your little friends but unfortunately I can’t offer any suggestions! I would just urge you to see a (ferret) vet and get both your guys checked out.
    I really hope that the diagnosis will be due to stress rather than illness and I thank you, from the bottom of my heart, from rescuing your ferrets from a horrible life with their previous owners
    If you remember, please let me know what the vet says?
    Big hugs to your two babies from their new friends down under :)
