Does anyone know the difference between the two?
I got the Frontline Top Spot from my vet ( I didn't know it was so expensive! Eek.) but I expected to get Plus.
I don't really know the difference, if there even is one?
Can anyone enlighten me, so I know in 6 months whether to stay with top spot or Plus.
I was going to use K9 Advantix, but the vet said it can be poisonous to cats which is not good since I have two!
Thank you
