Hamster Diseases

Bacteria-causing diseases may often be caused by bad living conditions.

A runny nose or visible wound are common symptoms of infections such as ringworm, or oral diseases caused by droppings into his mouth and food that is poorly chewed up.

Hygiene Neglect

Some hamsters may fail to defecate correctly.

Because the hair gets soaked with body oils, it is warm and the hamster does not dry off very easily.

Hamsters, on the other hand, instinctively know to bathe themselves and play in the water.

If they do not, it could result in smelly feet and a stinky hamster that smells of pee.

Aside from that, common diseases that hamsters get are bacterial and viral infections that bring about skin rashes and scaly skin, which if left unattended.

When their rhythm slows, they become susceptible to other diseases like pneumonia or diarrhea.

Hamster Scent Glands

Because of the scent glands, you might also be wondering why does my hamster smell so bad.

Remember that this is totally normal and they will not suffer from any diseases because of this.

When a female hamster is in heat, she may rub her scent glands on the sides of the cage when she is feeling cranky or aroused.

She can also receive her period and the odor will remain in her hair and skin for a day or two.

The pheromones may dissipate if the hamster is given a bath or is brushed regularly.

Farts Caused by a High-Protein Diet

Hamsters are unable to burp because they have a shortened esophagus and stomach.

Instead, they would pass gas, which, if stinky enough because of the excessive amount of protein in the diet they have, can produce the ammonia smell associated with animal urine and feces.

If you feed your hamster high-protein foods like chicken or rat food, you can expect the ammonia smell from their body to make its way to your hamster’s cage and your home.

Dirty Enclosure

Another reason your hamster may smell so bad is because of a dirty cage.

Hamsters pee to eliminate waste, and if there is not enough substrate to absorb their urine and they urinate on their sleeping area, they can smell it and crawl over that area and pee. When their urine dries up, you can smell it more.

Furthermore, aged hamsters will rub their scent glands on the sides of the cage when they feel cranky or aroused.

Urine normally has a mild odor, but if your hamster’s cage is smelly, it can smell like ammonia or rotten eggs because ammonia is a byproduct.
