Collapse

Synonym(s): Weakness

Contributor(s): Kyle Braund, Kate Murphy

Introduction

  • Cause: it can be very difficult when first presented with a cat that has had 'a funny turn' to establish the etiology. Cats are more challenging than dogs in this respect since the signs are often more subtle and acute decompensation of chronic diseses is not uncommon.
  • Diagnosis:
    • It is vital to take a complete history from the owners and if the episodes are recurrent to ask them to collect further information during subsequent episodes, eg heart rate, mucous membrane color (more challenging for an owner of a cat to do), responsiveness.
    • Unless episodes are occurring sufficiently frequently it may be impossible to see one yourself.
    • Ask the owners to video an episode if it occurs at home and, if not possible, ensure they give you a very detailed description of the event and that you listen with an open mind.
    • Collapse is a diagnostic challenge and many tests will yield negative results and thus achieving a definitive diagnosis may be impossible.
    • Examination of the cat as close to an episode as possible, ideally during, or shortly after an episode, may be most useful.
