A cat has become less active, reluctant to jump, and shows an unkempt appearance. Which condition should you be suspicious of?

• A. Osteoarthritis
• B. Obesity
• C. Hyperthyroidism
• D. Diabetes

Answer: (A)

Pain in the joints from osteoarthritis is a common reason a cat becomes less active and hesitates to jump. When joints hurt, the cat avoids movements that aggravate the pain, leading to a fall in overall activity and reluctance to leap up to perches or into cozy spots. That same discomfort can cause the cat to groom less thoroughly, resulting in an unkempt appearance. In aging cats, this pattern—reduced activity, avoidance of jumping, and a dull or unkempt coat—fits osteoarthritis particularly well because it directly reflects joint pain and the resulting change in daily behavior. Other conditions can cause lethargy or coat changes, but they don’t explain this specific combination as cleanly. For example, obesity can reduce activity but doesn’t inherently drive an unkempt coat; hyperthyroidism often brings weight loss and sometimes increased activity rather than reduced activity; diabetes may cause lethargy and coat changes but is typically accompanied by increased thirst and urination and weight shifts.
