Kidney Disease in Cats
Your cat’s kidneys are little janitors for your kitty’s bloodstream, pushing blood around the body and sending waste through the urine. They help regulate blood pressure, filter metabolic waste, and produce hormones and blood cells. Unfortunately, chronic kidney disease is a common ailment in older cats, and cats are naturally very susceptible to conditions that can later affect the kidneys if they have a history of urinary tract infections or kidney stones. This issue is more common in cats as they have more frequent bladder infections that can spread to the kidneys.
Kidney disease in cats
When the kidneys and their complex filtering system break down, waste products can trickle into the bloodstream, which can cause systemic complications.
There are two broad categories:
- Acute kidney failure (or injury) or chronic kidney disease. Acute kidney injury is a severe condition with a relatively sudden onset, while chronic kidney disease develops over a period of time. Acute kidney failure can be caused by ingesting poisonous or toxic substances (pesticides, antifreeze, certain plants like lilies, cleaning fluids, ibuprofen), as well as physical blockages to the kidney that prevent blood flow. If caught early and treated immediately, kidney damage resulting from acute kidney injury is potentially reversible, although the prognosis for cats with major kidney issues varies greatly.
- Chronic kidney disease must be managed daily and may have no cure.
Symptoms of kidney disease in cats
Acute kidney failure signs include seizure, vomiting, bad breath, weakness, and loss of coordination.
Cats rarely have visible signs of kidney disease early on, which is why early diagnosis can be challenging. In later stages, signs of kidney disease may include increased thirst, increased urination, weight loss, decreased appetite, lethargy, and, in some cases, vomiting. If these signs are observed, a pet parent should seek veterinary consultation at once.
Diagnosis and treatment for cat kidney disease
If kidney disease is suspected, a veterinarian will run blood tests and a urinalysis to confirm function and damage of the kidneys. Depending on the results, treatment is either immediate (for acute kidney failure) or scheduled, progressive therapies (for chronic kidney disease). Some cats are rehydrated through IVs and sent home with instructions for maintaining a special diet that helps support kidney function, whereas cats that have undergone transplants or injury undergo dialysis at feline veterinarian specialty centers.
Bladder infections & kidney disease
Bladder infections can turn into kidney problems very quickly. Preventing UTIs is the first step toward healthy kidneys for cats, so remember to always have fresh water for your cat, make sure they have a clean litter box, and keep them at a healthy weight. It is also possible that what you think are UTI symptoms could be kidney stones, so a trip to the vet isn’t a bad idea!
Kidney disease and conditions are manageable in cats if the diagnosis isn’t life-threatening. However, it is a serious ailment that can have dire consequences. However, since kidney complications are prevalent in cats, especially seniors, your knowledge of the symptoms and the proper diagnostics would be your cat’s lifesaver.
