Just looking for some opinions. I have an indoor only cat that is around a year old. I started her on Advantage, and then switched to Revolution thinking about ear mites, heart-worms etc. I am on a fixed income, which just got lowered due to a long bout with Covid 19 and recovery. My question is this, I have looked a the cost of Revolution, which is pretty high, and thinking about returning to Advantage 2 mainly for flea control. Wondering how other cat lovers feel about this.
