1. Patient Background

Species: Feline    Sex: Female   Age: 4 Months   Weight: 1.5kg  

Chief Complaint: Purchased from a pet store with unclear vaccination and Parasite Prevention History, the cat developed loose stools on the first day after being brought home. The condition got worse after 4 days, with clinical signs such as vomiting, fever, and poor appetite.

2. Treatment Process

Clinical examination revealed that the affected cat had foreign body pneumonia and intestinal distension, and was hospitalized for treatment. During hospitalization, symptomatic drug treatment was administered. After one week, the cat's mental state and appetite returned to normal, but the stools remained loose and soft. A few days later, the cat continuously passed watery stools and intestinal mucosa, accompanied by vomiting, and was diagnosed with feline coronavirus infection. Symptomatic drug treatment was administered, and the cat's condition improved after 3 days, with formed stools. However, 2 days later, the cat again passed intestinal mucosa, the frequency of defecation increased, and the stools were bloody. The cat's mental state deteriorated, and it lost its appetite. Drug treatment was continued for 5 days, but there was no improvement, and diarrhea persisted.

3. Laser therapy treatment plan

After a series of unsuccessful treatments, Laser therapy was attempted.

Protocol Setup：Preset Protocol

Laser treatment frequency: Once daily for 3 consecutive days, followed by twice weekly treatments (adjusting the frequency of treatments based on the progression of the disease).

4. Results

Day 1 of laser treatment: The cat's spirits improved significantly.

Day 2 of laser treatment: The frequency of diarrhea decreased, and appetite recovered.

Day 3 of laser treatment: The cat started to pass soft stools without mucus.

Day 4 of laser treatment: The frequency of soft stools decreased, with good spirits and appetite, and the cat became more active.

5. Discussion

In this case, a significant component of the cat's diarrhea was caused by coronavirus. While the mortality rate of this disease is not high, diagnosis can be difficult, and it is characterized by recurrent episodes and difficult prevention. Through the above tortuous treatment process, we have seen the limitations of drugs in the treatment of viral diseases. Kittens may also experience gastrointestinal discomfort when taking medications. In such difficult-to-cure situations, the choice of laser therapy produced very surprising results.

Coronavirus can cause enteritis and gastrointestinal inflammation, and one of the most important effects of laser therapy is to reduce inflammation. Inflammation is the result of damage to blood vessels and cells. Laser therapy can generate nitric oxide and other mediators that stimulate vasodilation, which helps to remove cellular debris and activate lymphatic drainage pathways. At the same time, reducing inflammation can have an impact on analgesia, which is why the affected cat gradually recovered its spirits and increased activity levels after laser irradiation.
