Wool sucking and wool eating in cats (Felis silvestris catus) (English)
Abstract [sv]

Yllesugning och ylleätning är relativt ovanliga beteendeproblem hos tamkatter. De har inte studerats i någon större omfattning trots att de har varit kända under lång tid. Det saknas välformulerade hypoteser som kan förklara de resultat som framkom i den hittills enda publicerade studien inom området. Därför genomfördes en Internetbaserad enkätstudie där 205 katter ingick. Resultaten tyder på att när en kattunge tas från sin mamma före 5-6 veckors ålder så kan det naturliga dibeteendet dröja sig kvar upp i vuxen ålder. Det riktar sig mot tyger i form av den orala stereotypin yllesugning. Ylleätning visade sig också röra sig om ett stereotypt beteende, men i det här fallet är det associerat med graden av objektlek som en katt ägnar sig åt. Graden av objektlek är högre hos yngre katter än hos äldre, och dessutom högre hos kattraser av sydöstasiatiskt ursprung än hos kattraser av annat ursprung. Graden av ylleätning visade sig följa samma mönster som graden av objektlek. Ylleätning tycks alltså röra sig om ett missriktat predationsbeteende. Det är fortfarande oklart om det finns ett samband mellan yllesugning och ylleätning eller inte.

Abstract [en]

Wool sucking and wool eating are comparatively unusual behavioral problems in domestic cats. They have not been studied much, despite having been known for a long time. There is a lack of well formulated hypotheses that can explain the results from the only published study about the subject thus far.  Because of that need, an internet-based survey with 205 cats was performed. According to the results, the natural suckling behavior can remain into adulthood when a kitten is taken from its mother before 5-6 weeks of age. The suckling behavior is directed towards fabric in the form of the oral stereotypy wool sucking. Wool eating turned out to be a stereotypic behavior too, but in this case associated with the degree of object play that a cat engages in. The degree of object play is higher in younger cats than in older cats, and also higher in breeds of Southeast Asian origin than in other breeds. The degree of wool eating turned out to follow the same pattern as the degree of object play. Wool eating thus seems to be a misdirected predatory behavior. It is still unclear if there is a connection between wool sucking and wool eating or not.
