Cat Mobility Assessment: Detecting Arthritis Early Through Behavioral Observation

Early arthritis detection in cats depends on behavioral observation rather than obvious lameness, with validated mobility assessment tools enabling owners to identify and report welfare-relevant changes.

Key Facts

Cats rarely limp from arthritis - their mobility impairment manifests as behavioral changes instead
The Feline Musculoskeletal Pain Index is a validated owner-completed questionnaire detecting arthritis
Key behaviors to monitor: hesitation before jumping, reduced jump height, sleeping in lower locations
The TUG (time to unwrap) test measures food motivation as a proxy for pain interference with activity
Cats with arthritis often show increased time spent in lower locations and reduced grooming of hindquarters
Solensia (frunevetmab) is a monthly injectable targeted specifically at feline arthritis pain
Meloxicam is effective but requires careful renal monitoring for long-term use in cats
Environmental modification reduces pain by eliminating the need for jumping or awkward positions
Monthly weight monitoring in arthritic cats tracks welfare impact - weight gain worsens joint load

Welfare Considerations

Feline arthritis assessment is owner-dependent in a way that cat health in general is not: owners who understand what to observe detect mobility changes that veterinarians seeing the cat briefly cannot. Validated questionnaires transform owner observation into objective welfare data that guides treatment decisions. The emergence of targeted anti-nerve growth factor antibody therapy (Solensia) has transformed feline arthritis treatment by providing effective monthly pain relief without the renal monitoring burden of NSAIDs. Owner education about behavioral arthritis signs is the most impactful welfare intervention at the population level.

What You Can Do

Complete a monthly feline mobility questionnaire to track changes in your cat's activity and behavior
Take monthly videos of your cat jumping onto furniture - changes in height and hesitation are detectable
Report any behavior changes suggesting reduced mobility to your veterinarian promptly
Ask specifically about Solensia if your cat needs long-term arthritis pain management
Modify your home environment: ramps, low-sided litter boxes, and ground-level sleeping options
Schedule six-monthly arthritis assessments from age 10 to detect changes before pain becomes severe
