Huh. My cats are indoor/outdoor, and so are the dogs. I get flea stuff for them but honestly I forget more often than not. Gotten fleas 1 time in all the years I've had them. Had no difficulty getting rid of them. When I live with my cats and I'm not on the ranch, they're indoor only, and I definitely never had fleas then.
Perhaps fleas in Australia have titanium exoskeletons and wear tiny little biohazard suits. I do keep hearing about how dangerous all the animals are there.
:thinking:
