My hamster died suddenly. What caused the yellow fluid and diarrhea?

Hi, it is difficult to tell what could have happened. Was she eating and passing feaces fine ? Did she eat anything unusual ? Hamsters can be quite delicate and in absence of obvious signs it can be tricky to find a cause for sudden death. Sorry she passed away so suddenly and soon, I hope your next friend will have many happy days ahead. Hope this helps.

I'm sorry for your loss. Unfortunately, without a necropsy (animal autopsy) it would be hard to say what caused Star to pass. If there was swelling and discharge from the ear, or from a gland on the body, the infection could have become septic and caused the passing, or there may have been an underlying illness or medical condition that caused it as well. It sounds like you were caring owners, so Star had a good life and lots of love while he lived. If you're having trouble coping with his passing, checking out some sources such as the Rainbow Bridge where you can make a pet memorial online may bring you some comfort.

I'm so sorry to hear this happened. I don't think that anything you did caused her death. I would not say that fluid pouch is "normal". It could be an abscess or a cyst which may or may not be related to her death. There is really no way to tell.

Thanks for reaching out about Hazel and am sorry for your loss. Increased water consumption could have been due to kidney, liver, uterine or endocrine problems. There is also psychogenic polydipsia (behavioral increased water consumption). Without an autopsy, an answer can't been given. Sorry again for your loss.

Diarrhea in hamsters is an extremely severe condition, most hamsters will not recover from it, you need to take him to the vet urgently if you want to try and save him, he will need fluid therapy as well as antibiotics.

Thanks for using Petco Pet Education Center, formerly Petcoach! This may be due to a gastrointestinal issue such as gastroenteritis, colitis, parasites, among other possibilities. I recommend that you have him evaluated by a veterinarian for further assessment and treatment. Good luck and have a great day!

I am sorry for the loss of little Dolores. Unfortunately, without a post mortem exam, the cause of her passing is difficult to determine. She may have been ill at purchase or suffered a trauma or toxicity in the time between purchase and her passing. I would suggest you contact PetSmart and inquire about their health guarantee and what to do next.
