On an indoor-only cat, no less! Never in 15 years have we needed a flea treatment or preventative, but apparently we did -- and do. Are they particularly bad this year or something? At any rate, what do you all recommend, especially for a topical? There are so many on the market, and I'm hearing that either the manufacturers have weakened them to lessen pet health risks OR fleas are becoming resistant to them. Please be specific re: brand name. Also, what's your remedy for a house infestation? It's horrible!
