What Does a Cat’s Foamy Urine Mean Mean?

According to the Mayo Clinic, proteinuria, or an abundance of protein in the urine, is a likely cause of foamy urine. According to Vetinfo, a high protein level in the urine may be a sign of serious illnesses such kidney disease.

Proteinuria frequently results from injuries to or disorders of the liver and kidneys, but the condition can also be a sign of a urinary tract infection, according to Vetinfo. Urinary tract infections can change the composition of urine and result in high levels of protein.

Cancer is one probable cause, as well as immune disorders that cause the body to attack its own tissue. As well as diabetic cats and cats with Cushing’s disease, certain cats are genetically predisposed to developing this ailment. It can be brought on by parasite infections such Lyme disease, heartworm, and lungworm.

Depending on the cause, the cat may also have other symptoms such as frequent urination, increased water intake, weight loss, decreased appetite, jaundice, and agitation, according to Vetinfo.

A veterinarian must examine the urine to diagnose proteinuria, and the severity of the condition is assessed by comparing the protein and creatinine levels. The underlying reason of proteinuria must be determined by additional testing, and the cause will determine the course of treatment. Cats with kidney disease benefit from a lower protein diet.
