Paisley has been doing great, and is now a year and a half old but we have been having one little problem. I really wanted some opinions about flea and tick treatments. Paisley was on Frontline for the first year of her life, but for the past couple of treatments she threw up several hours after I put it on her. Last time she actually threw up multiple times. I talked to my vet about it, and the other option he recommends (and that they have in stock at the office) is bad for cats. Considering Paisley's best friend is her kitten George, that doesn't really work for us. I was wondering if you all could share some other options, as I really hate to not treat her at all, but at the same time, I feel like I am poisoning her.
