Our order for profender spot-on wormer for cats arrived within the time they promised, the package was in good condition, and the product worked as expected. This is the same stuff our vet uses. They charge us $28.00, plus the $50.00 for an office visit. If you have cats who are happy to eat food with powdered remedies in it, you have options. We have two cats who will not take their medicine (or won`t keep it down, if made to take it), and profender makes all of us happy--especially now that it`s affordable.
