Feline Lip Blisters

Feline lip blisters may be caused by excessive heat, oral ulcers, or infection with the feline calicivirus. If not treated promptly, this condition may worsen and affect your cat's appetite. Therefore, it is recommended that owners take their cats to a veterinary hospital as soon as they notice the symptoms to receive appropriate diagnosis and treatment.

Heatstroke

If your cat's usual diet is relatively dry, and it drinks little water, it is prone to heatstroke, which can cause lip blisters. Symptoms may also include dry nose, red eyes, yellow urine, and dry stool. To address this, reduce the amount of high-protein food fed to your cat and help it cool down by feeding appropriate fruits and vegetables or increasing its water intake. If diet adjustments are ineffective, consider administering cooling agents.

Oral Ulcers

When a cat has oral ulcers, it may develop blisters on its lips or gums, which are a manifestation of the ulcers. Other symptoms include long-term production of thick saliva, loss of appetite, swollen gums, and mouth pain. Carefully examine your cat and seek professional veterinary care if you suspect oral ulcers.

Feline Calicivirus

After being infected with the feline calicivirus, a cat may exhibit symptoms such as sneezing, coughing, decreased appetite, lip blisters, and oral ulcers. This is a serious condition, and it is recommended that owners have their cats tested for the virus. If the infection is confirmed, administer appropriate ulcer treatment while also using interferon, which can inhibit virus replication.
