Ugh, so the one that treats a large variety and the tape worms is the vetafarm worm out gel but I can't get it on amazon and I don't know if I can get it at tractor supply or petsmart. I'll look there but couldn't you use like a liquid goat wormer or something? I thought there were more options than just that. I tried a horse wormer on one hen that I thought had worms.
You could try goat wormer, but it might not work, and you would have to give it orally for several days in a row. Petsmart, Petco and Tractor should have some type of dog/cat wormer with praziquantel, but it will be very expensive. Least expensive way to treat tapes is with an ivermectin/praziquantel horse product.
