Associations between body condition and disease in cats

Area of Science:

• Veterinary medicine
• Animal health
• Feline studies

Background:

• Body condition significantly impacts feline health.
• Obesity is a growing concern in domestic cat populations.
• Understanding the link between weight and disease is vital for preventative care.

Purpose of the Study:

• To investigate the association between various body conditions and the incidence of specific diseases in cats.
• To compare health outcomes in cats of different body conditions against those with optimal weight.

Main Methods:

• A prospective study involving 1,457 cats from veterinary hospitals in the northeastern United States.
• Body condition was assessed using 6 silhouettes (cachectic, lean, optimally lean, optimal weight, heavy, obese).
• Health data and body conditions were tracked for 4.5 years, with data collected via medical records and owner interviews.

Main Results:

• Heavy cats were 2.9 times more likely to experience lameness.
• Obese cats showed increased risks for diabetes mellitus (3.9x), nonallergic skin conditions (2.3x), and lameness (4.9x).
• Thin cats (cachectic, lean) had a 1.7x higher likelihood of veterinary visits for diarrhea.

Conclusions:

• Excess body weight in cats is associated with significant health risks, including diabetes, lameness, and skin problems.
• Weight management in heavy and obese cats can mitigate these health risks.
• Underweight cats are more susceptible to diarrhea without a clear diagnosis.
