Cerebellar Hypoplasia in Cats: Welfare and Quality of Life

Cerebellar hypoplasia is a non-progressive neurological condition in cats caused by feline panleukopenia virus exposure in utero, with welfare that is better than commonly perceived.

Key Facts

Cerebellar hypoplasia results from feline panleukopenia virus destroying developing cerebellar Purkinje cells, causing permanent ataxia
Severity ranges from mild head bobbing to severe inability to walk — the condition is static and does not progress
Cats with cerebellar hypoplasia have normal cognition, normal pain sensation, normal vision and normal social drive
Quality of life assessments consistently show that even severely affected cats can have excellent welfare with appropriate owner support

Welfare Considerations

Cerebellar hypoplasia is frequently misjudged from a welfare perspective — the dramatic ataxia is distressing to observe but does not indicate pain or progressive neurological decline. Affected cats adapt well to their neurological limitations and can lead full social and play lives with appropriate environmental modification. The primary welfare risks are secondary injuries from falls and owner decisions to euthanase based on appearance rather than welfare assessment. Non-slip flooring, padded furniture edges and ramps substantially reduce injury risk.

What You Can Do

Provide non-slip flooring throughout the home to reduce fall frequency and injury risk
Install padded furniture corners and use padded beds at floor level to prevent fall-related injuries
Assess quality of life based on the cat's own behaviour — appetite, play, social engagement and comfort seeking — not appearance of movement
