I heard they got busted 
I agree. Lots of stories of vet refusing meds single dose.That is a shameI never got to order from them.
It was a good feeling to know you had them as a backup if you couldn't find or get a certain med for the animals. Hope its only temporary.
A couple weeks back someone on here said they were indeed closing...,Maybe they are on vacation. There was is something saying that they will be closed during a certain span of time and it was missed ?
