My cats all wear collars . They are also of the elastic type ; they cannot get choked ... . I buy those with a tiny bell on it . This is the only reason why they are wearing their collar : I can always here where they are ... ! I feel more at easy knowing this ! Of course , I take Inka's collar off , everytime I comb her hair (she is a long-haired kitten ; looks like a Main Coon) .
