Hi @hanen, just told @catwoman a secret from down under. Save on flea collars and treatments. Find a bottle of Emu oil. Emu is ostrich like Australian native bird. Two drops of oil on back of neck skin deep, not outer fur, and your cats should become flea free. How long¿ depends on cat and flea environment, but that's same with commercial stuff. It supposed to work with dogs too, so find source of Emu oil. Can be ordered probably from Aussie. Maybe set up mkt stall and sell to dog and cat owners your locality¿ 😆
