Highly stable individual differences in the emission of separation calls during early development in the domestic cat.

摘要: Study of the development individuality is often hampered by rapidly changing behavioral repertoires and need for minimally intrusive tests. We individually tested 33 kittens from eight litters domestic cat in an arena 3 min once a week first 3 postnatal weeks, recording number separation calls duration locomotor activity. Kittens showed consistent stable individual differences on both measures across within trials. Stable emission trials emerged already 10 s testing, activity 30 s. Furthermore, kittens' calls, but not their activity, was highly conclude that provide efficient, reliable measure behavior during cat, possibly other species emitting such calls.
