An investigation on the influence of feline flea allergy on the fecundity of the cat flea

Document Type


Publication Date



Survival, egg production and egg viability of fleas allowed to feed on eight flea-allergic and six flea-naive cats were compared. Fifty fleas, in feeding cages or free roaming, were allowed to feed on the cats. Flea-allergic cats removed significantly more free-roaming fleas than did flea-naive cats. Female fleas produced fewer eggs on flea-allergic cats than on flea-naive cats regardless of feeding method. There was no significant difference in egg viability between the two groups. The data suggest that flea-allergic cats efficiently removed fleas by grooming and that they also produce unknown factor(s) that affect the fecundity of fleas.
