Many guinea pig homeowners know their pets critically need to have every day exercise outside their cage in an effort to keep in better health. Building or buying a secure indoor run is a great possibility for allowing guinea pigs the space they should actually run round, train, maintain their minds occupied and keep fitter.
Phylogenic sources of worry include such triggers as pain, rapid stimulus change, sudden actions, heights, isolation, loud noises, strangers, hearth, water, and unfamiliar environmental and social conditions. Whereas ontogenic sources of worry are mostly the result of learning and experience. Pathogenic fear (generalized nervousness and phobia) happens when the fearful arousal can’t be avoided or escaped. Dogs which might be pathologically anxious or phobic, are unable adaptively to escape or avoid fearful arousal. So these canines labor futilely under the influence of escalating concern and anxiousness.
