Frenetic random activity periods


Frenetic random activity periods, also colloquially known as zoomies, scrumbling, midnight crazies, or mad half-hours, are random bursts of energy occurring in dogs and cats in which they run frenetically, commonly in circles. They usually last a few minutes or less. It is not known what causes animals to engage in FRAPs. Some veterinary experts have noticed that FRAPs are often associated with times of transition, such as the return of an owner. Other non-domestic animals are also known to experience FRAPs, such as polecats and elephants.
Although little data exists regarding the safety of FRAPs, ethologist Marc Bekoff has suggested that dogs should be allowed to freely engage in them as long as the dog is in a safe area and will not harm others or themselves. Likewise, FRAPs are normal and healthy behavior for cats as well.

Description

FRAPs are characterized by an abrupt onset of rapid, seemingly random movement. Typical features include running at top speed, rapid turns and spins, jumps and sudden stops, and brief vocalizations or tail-posture changes. Episodes usually last from a few seconds up to several minutes and end as abruptly as they began. FRAPs most often occur when an animal is in a familiar environment and appear to be self-terminating. FRAPs are common in puppies and kittens but occur in animals of all ages. Recurring contexts in which FRAPs are commonly observed include immediately after elimination, following bathing, at dawn or dusk, during or after play, when an animal has just been released from confinement, or upon the return of an owner. These associations are observational rather than causal, and the proximate triggers for individual episodes are not fully understood.

Hypotheses

  • Energy discharge: FRAPs may be a rapid release of pent-up physical energy after a period of rest or confinement.
  • Emotional expression : Some ethologists suggest FRAPs express excitement, joy or a positive arousal state. Marc Bekoff, among others, interprets many such episodes as play-related and pleasurable.
  • Ontogenetic / practice function: In young animals, frantic bursts of activity may be part of normal motor and behavioural development, allowing practice of locomotor and predatory skills.
