Cats are prone to developing resorptive lesions with their teeth. Although the exact process is still not well understood, they literally resorb, or form holes, in the root and/or the crown of the tooth. If this process takes place above the gumline, the nerve is exposed and the patient experiences discomfort. If a lesion occurs below the gumline, they typically are not aware of it, but it can eventually progress above the gumline or cause the tooth to weaken and break off.

Dental radiographs and a thorough oral examination under anesthesia are required to identify any lesions and address them appropriately. If the body has resorbed the root and left only the crown, we can remove the crown and seal up the gumline. If the root is intact with a damaged crown, the procedure is more involved, requiring a full extraction of the unhealthy tooth.

If you think your cat is experiencing dental discomfort, please contact us immediately.

You assessed your cat's body condition score (BCS) to be to be 3 out of 9.

What does this mean? The BCS is an assessment of your cat’s general body composition, including muscle and fat. While a score of 4 to 5 is ideal, a BCS of 3 indicates that your cat is thin.

What to do next: While thin cats are generally at lower risk for serious health issues compared to overweight cats, being underweight can lead to decreased muscle mass, malnutrition, and a weakened immune system. Unless there is an underlying reason for your cat’s thinness, the situation can often be improved with simple lifestyle adjustments, such as:

  • Offering a palatable diet recommended by your veterinarian
  • Feeding small, frequent meals
  • Stimulating the appetite by warming the food or introducing toppers
  • Minimizing stress
  • Weighing your cat monthly
  • Re-checking your cat's BCS at home
  • Staying alert to other health changes (especially continued weight loss and appetite loss)

Your cat's BCS provides valuable insights into their overall health and helps us spot potential issues early. While a BCS of 3 isn’t an immediate cause for concern, it’s a sign that small adjustments to their feeding and care routine could have a positive impact on their health.

Questions? We can help. Let’s work together to score a win for your cat's health.

You assessed your cat's body condition score (BCS) to be to be 6 out of 9.

What does this mean? The BCS is an assessment of your cat’s general body composition, including muscle and fat. While a score of 4 to 5 is ideal, a BCS of 6 indicates that your cat is borderline overweight.

What to do next: Simple daily actions can help prevent your cat from becoming overweight. Even a few extra ounces or pounds can significantly impact their health, increasing the risk of serious conditions like diabetes, arthritis, and kidney disease.

Restore your cat's future health by:

  • Feeding portioned meals (Your veterinarian can assist you with how much to feed)
  • Reducing stress by minimizing household changes and maintaining a routine
  • Decreasing boredom with interactive toys, social interaction, and cat furniture
  • Separating pets during meal time (Consider a microchip-linked feeder for multi-cat households)
  • Weighing them monthly
  • Re-checking your cat's BCS at home

Your cat's BCS is like a warning light for their future health. Taking proactive steps to address your cat’s weight can minimize future complications and help ensure they stay fit, agile, and healthy.
