When a hamster gets sick, the first step is to carefully observe its symptoms and take corresponding measures based on those symptoms.
Cold
When a hamster catches a cold, it may show symptoms such as cold paws and a lack of energy. Treatment methods include feeding it Banlangen (a traditional Chinese medicine for colds) or adjusting the environmental temperature to 22 - 26°C. If the hamster is sneezing but not流鼻涕 (assuming you meant "has no runny nose"), it may be an allergy caused by dust in the food or wood shavings.
Diarrhea
When a hamster has diarrhea, its feces may become thin or watery. The causes could be improper diet or a gastrointestinal infection. For treatment, you can adjust the diet and supplement with probiotics. If the symptoms persist, seek medical attention promptly.
Eye Infection
When a hamster's eyes are red, swollen, teary, and accompanied by discharge, it may be due to an unclean environment or scratches from its claws. In terms of treatment, clean the eyes and use a mild anti-inflammatory drug. Also, keep the environment clean.
Skin Disease
Skin problems may manifest as red and swollen skin, hair loss, or dandruff. To treat this, avoid allergens and use anti-allergy or anti-inflammatory ointments. Ensure that the living environment is dry and clean.
Dental Problems
If a hamster is drooling and has a decreased appetite, it may be due to overgrown or crooked teeth. Providing regular opportunities for chewing is a preventive measure. If necessary, seek help from a veterinarian.
Fractures and Sprains
Difficulty walking or joint deformity may be caused by a fall or a fight with other animals. For treatment, immobilize the injured area and give oral anti-inflammatory and pain-relieving medications. In severe cases, consult a veterinarian.
Otitis Media
Frequent head shaking or ear scratching may be a sign of an ear infection. Treatment involves cleaning the ears and using anti-inflammatory ear drops. Also, maintain environmental hygiene.
Diabetes
An increase in drinking and eating, along with sticky urine, may indicate diabetes. Treatment requires adjusting the diet and increasing exercise. In severe cases, consult a veterinarian.
Tumor
The appearance of an unknown lump on the body may be a sign of a tumor. Treatment may require surgical removal and a pathological examination.
Heart Disease
Difficulty breathing and obvious abdominal movement may be symptoms of heart disease. Treatment involves adjusting the diet and using relevant medications.
Preventive measures include maintaining environmental hygiene, having a reasonable diet, conducting regular check-ups, and providing sufficient exercise and entertainment facilities. These measures can help reduce the risk of hamsters getting sick.
