A cat with a veterinarian

Medically reviewed by Dr. Zac Pilossoph, DVM 

For this annual report, we dove into Healthy Paws’ claims records to find out what the most common cat health conditions were and how much treatment costs on average so that pet parents would be aware when adopting a cat. 


1. Gastritis – stomach issues

Average cost estimate: $1,500-$1,800
Makes up 27% of top ten claims for cats

Gastrointestinal (stomach) issues can be caused by a few primary conditions, including gut inflammation, ingesting an inedible object or toxic substance, parasites, infections, some types of cancer, and other serious illnesses. Keep an eye on what your cat eats; life-threatening emergencies happen when cats ingest strings, tape, other linear objects, and several household plants.

Symptoms may include:

  • Prolonged vomiting
  • Diarrhea
  • Anorexia and weight loss
  • Abdominal pain
  • Bloating
  • Constipation
  • Dull coat
  • Excessive thirst

Common treatments/diagnostics the Healthy Paws plan insures for gastrointestinal issues include:

  • Diagnostic tools:
    • Lab tests
    • FIV and Leukemia testing
    • X-rays
    • Ultrasound
    • Endoscopy
  • Antibiotics
  • Probiotics
  • Parasitic treatments
  • Stomach surgery

Ryder the cat

Ryder, a young orange cat, aka “trash cat,” loves to eat. This appetite caused him to consume a chunk of rubber, sending him to the emergency vet. The object was removed during surgery, but complications meant a three-day hospital stay. His pet parents were reimbursed $6,747 by Healthy Paws.


2. Urinary tract infections (UTIs) or Feline Lower Urinary Tract Disease (FLUTD)

Average cost estimate: $1,050
Makes up 13% of top ten claims for cats

Cats are more prone than dogs to see the vet for urinary problems, which have similar symptoms like urinating small amounts frequently and having accidents outside the litter box regardless of the underlying cause. FLUTD describes a variety of conditions that affect the bladder and urethra of cats. Infections are more common in much older cats and those with underlying health problems like diabetes, while younger cats often develop an inflammatory condition called idiopathic cystitis or develop urinary bladder stones. The underlying cause is due to multiple factors: bladder and hormone abnormalities, environmental stressors, infections, and urinary stones or sand, which may obstruct the normal flow of urine.

Symptoms may include:

  • Painful urination or straining to pee
  • Bloody or cloudy urine
  • Frequent trips to the litter box or urinating outside the box
  • Constant licking of the genital area
  • Lethargy
  • Vomiting or diarrhea
  • Hard or distended abdomen
  • Poor appetite
  • Low energy
  • Decreased social interaction 

Common treatments/diagnostics the Healthy Paws plan insures for UTIs and FLUTD include:

  • Diagnostic tools:
    • Lab tests (urinalysis)
    • X-rays (to screen for blockages)
    • Ultrasounds 
    • Urine culture 
    • Bloodwork
  • Antibiotics
  •  Pain medication
  • Laser therapy
  • Surgery, including perineal urethrostomy (surgical bypass of the urethra, sometimes performed after chronic urinary blockages
  • IV fluid therapy
  • A urinary catheter
  • Medications for pain and swelling.
  • Hospitalization

Checkers the cat

Checkers the cat was straining to pass urine and his bladder was the size of a lemon. Checkers required emergency surgery to remove a blockage in his urinary tract and fully recovered. His pet parents were reimbursed $1,860.


3. Skin conditions

Average cost estimate: $200-$2,500
Makes up 10.4% of top ten claims for cats

Cats can be afflicted with a myriad of skin conditions, such as infections, parasites or allergies. The most common symptoms are itchiness, dry or flaky skin, hair loss, and over-grooming. A vet can identify a cause through diagnostic tests and start a treatment plan.

Symptoms may include:
• Scratching, itchy behavior
• Dry, flaky skin or dandruff
• Cuts, wounds, abscesses and sores
• Over-grooming

Average cost estimate: $1,500
Makes up 9.4% of top ten claims for cats

Heart issues in cats can include hypertrophic cardiomyopathy, complications from blood clots, and heart valve issues. There is no cure for heart disease, but most heart conditions can be managed for a period with medications. It is important to know that early heart disease will not often show outward signs. A veterinarian can often detect heart changes much earlier in the disease process, making it crucial to have your cat evaluated annually.

Symptoms may include:

  • Coughing or difficulty breathing
  • Rapid breathing
  • Weakness
  • Lethargy
  • Decreased appetite
  • Weight loss
  • Sudden paralysis of one or more legs (due to blood clots)

    • Blood pressure monitoring
    • Electrocardiogram (EKG)
    • Echocardiogram
    • X-rays
  • Medications: Diuretics, drugs to relax blood vessels, drugs to help the heart muscle function more effectively, and anti-clotting medication.

6. Infections

Average cost estimate: $300-$2,000
Makes up 7.5% of top ten claims for cats

Various types of infections can affect cats and their major organs. Infections can be transmitted by exposure to another animal with the condition, drinking or eating contaminated water, food, or soil, an insect bite, open wound, or an infected mother to her kittens.

  • Fungal infections – Funguses (Aspergillosis, Candidiasis, valley fever, Cryptococcosis) live in the dirt and can infect cats when they eat or sniff contaminated soil. Fungal infections do not respond to antibiotics.
  • Parasitic infections come from tick or flea bites and include hemoplasmosis, Babesia, Hepatozoonosis and Surra.

7. Diabetes

Average cost estimate: $1,600
Makes up 6.9% of top ten claims for cats

Cats commonly develop type II diabetes mellitus. Most diabetic cats are initially overweight, which leads to insulin resistance—a reduced ability of cells in the body to respond to insulin. Insulin resistance results in abnormally high blood sugar levels. Left untreated, diabetes can lead to weight loss, loss of appetite, vomiting, dehydration, coma and even death. Diabetes can be controlled with insulin injections, dietary management, and weight loss. Sometimes, Type II diabetes can be reversed and cats go into remission.

Symptoms may include:

  • Excessive thirst and urination
  • Vomiting
  • Oily, dandruff-laden coat
  • Lethargy

Common treatments/diagnostics the Healthy Paws plan insures for diabetes include:

8. Cancer

Average cost estimate: $3,000-$5,000
Makes up 6.7% of top ten claims for cats

Cancer is caused by the rapid division of cells that often form masses or tumors in various parts of the cat. While it mainly occurs in older pets, it can happen at any age. It can be found in almost every part of the body, from the bones to the brain. It can be hard to detect early in cats as they tend to hide signs of discomfort. The earlier the cancer is caught, the better the chances of successful treatment.

Symptoms of cancer may include:

  • Lumps or masses
  • Lack of appetite or weight loss
  • Difficulty urinating or defecating
  • Fluid discharge or bad odors 
  • Limping or lameness
  • Sores that do not heal

Average cost estimate: $100-$175 for simple cases

Makes up 5% of top ten claims for cats

Outer ear infections can be painful and annoying, but if they persist to the middle or inner ear, they can lead to neurological damage and deafness. Recurrent bacterial or fungal ear infections often have underlying causes, such as allergies, yeast, bacteria, abnormal ear anatomy, or ear canal tumors. Chronic ear infections can lead to a painful “aural hematoma”, when blood vessels in the ear flap burst causing it to fill with bloody fluid.

Symptoms may include:

  • Head shaking
  • Scratching at the ear
  • Offensive odor in the ear
  • Redness or scabbing inside the ear
  • Ear is hot to the touch
  • Ear is painful/sensitive

Claim of Fame

Rocky, domestic shorthair, seven years old

Total claims: $152,638
Healthy Paws reimbursed: $121,610

Coverage: Reimbursement based on covered treatments using an 80 percent reimbursement level and a $250 annual deductible.

Rocky, a cat, had a rough year, developing several conditions that required expensive vet care. It started in July, when he stopped eating, acted lethargic and limped. His pet parent took him to the vet where they ran a number of diagnostic tests and eventually determined he had a cancerous mass in his abdomen that had spread to his organs. He required a surgery where the doctors make an incision in the chest wall to access the organs inside the chest. During the surgery, doctors discovered he had nerve paralysis, fluid around the lungs, and eye ulcers.  After the surgery, he was hospitalized on oxygen and supportive care including blood transfusions, anti-nauseants, antibiotics, and other medications to treat the other conditions. While on the ventilator, he developed pneumonia, which also needed treatment. Rocky survived all his medical emergencies and is still recovering at home, being fed through a feeding tube, said his pet parent.
