Gawd it's a horrible year for fleas up here. I've only found one on Allie (indoor cat), but every day find two or three on Mitzi despite her regular trips to the groomers, frequent washing of her bedding, use of diatomaceous earth on bedding, in crates, and on the only carpet in the house. Mitzi is a frail 15+ years old, weighs 8 pounds, in renal failure, so there is no way I will use chemicals on her, but also no way I can let the fleas use her for breakfast, lunch and dinner.
She's also hypersensitive to smells, so I'm not sure what flea-repelling essential oils might be least offensive to her. Ideas, please?
