Can anyone recommend any effective and cheapish flea treatment for the cat and the house, please? We have treated the cat with Johnsons tablets, and shaken flea killing powder over all the downstairs floors, but the problem seems to just lessen for a few days and come back again. The house stinks of flea treatment, even after the stuff is hoovered up, and the poor cat is itching again - I do comb her almost every day, and crush any fleas I get out then. Please help!
