My (indoor) cat contracted fleas about a month ago and I used the Zodiac spray on the carpet, upholstery, curtains, and mattresses as I went about treating the apartment. I also used the Zodiac sponge bath (2 treatments/bottle, used both) and one course of the Frontline topical medicine. Today I was brushing my cat and found more fleas. My vet informed me that they have heard nothing but complaints from pet owners who've used the Zodiac products.The label claims that: "One treatment gives continuous protection against pre-adult fleas for 7 months." I used the spray generously but here I am 1 month later right back where I started.Just treating my 2-bedroom apartment for fleas is a costly and tedious task. If you're going to go through this, make sure you use the BEST products available. Talk to your vet and explore ALL your options. GOOD LUCK!
