CO, control diet, without supplemental fibre; SF10, supplemented with 10 % sugarcane fibre; SF20, supplemented with 20 % sugarcane fibre; CEL10, supplemented with 10 % cellulose.

^a,bMeans in the column not sharing a common lower case differ (P < 0·05).

^A,BMeans in the row not sharing a common upper case differ (P < 0·05).

*Standard error of the mean, n 8 cats per diet.

^†Linear or quadratic effect of sugarcane fibre inclusion. Orthogonal contrast = CEL10 v. CO + SF10 + SF20.

^‡No time × diet interaction (P > 0·05), results are the mean of the times of evaluation.

^§Tricobezoar sizes: small, <1 cm; medium, from 1·1 to 2 cm; large, >2·1 cm.

^‖Time × diet interaction (P < 0·05), results compared considering the time and diet effects.
