I think that vet tech better get her information straight.

When I was at the vets with Poppy on wednesday, there was a guy there that needed Advantage for his cats. He has 4 of them.
The vet tech gave him the advantage for dogs and 1 tube is good to treat 4 cats. So he saved by doing it this way as where I am, 1 tube of Advantage for a cat is $13.45 and 1 tube for a dog is $15.00. So instead of him paying $53.80 for 4 tubes for cats, he paid $15.00 for 1 tube for dogs and as you said Debbie, it is the exact same thing.
