I'm glad! Dr. Frye's prices are pretty affordable, and I would be very wary of buying it off the internet. Most times you need a prescription (and if you don't, it's more than likely out of the country...) and it's just not safe due to dosages and strength. Dr. Frye will give you the amount that you need along with proper instructions. I paid little over 30 including shipping, which will probably amount to the amount you would pay at an online venue anyway.

It depends on the infestation of worms. Sometimes you can and sometimes you can't.

Exactly what Heatheranne mentioned about the liqui-cal! You can usually find them at pet shops. I know Petco has it, at least.
