Tapeworms, need praziquantal without RX

Icare for 4 feral cats and usually got tapeworm meds at tractor supply but they have stopped carrying it. Was wondering wondering if anyone knows where i can get some without a prescription.

I found two that contain the same active ingredient on Amazon  
The cheaper option is this one 

eBay is a good source.  They have both brand name and generic available.  Here are a couple of them.

This one costs $27.99 for 3 tablets.

http://www.ebay.com/itm/20-Capsules...546576?hash=item2a67874c50:g:6IoAAOSw3mpXMV0u

This one costs $12.99 for 20 capsules.

Also, if you want one like Drontal that gets regular worms PLUS tapeworms, you can get BIHELDON tablets.  They contain the prazquantel AND the pyrantel pamoate just like Drontal.  If you buy from Bulgaria, you get a package of 30 tablets and for most cats the dose is 1/4 to 1/2 a tablet.  Tastes bad so I break it up and put in a capsule.  Pill pockets might work too.   I got some from a UK seller for $6.79 recently.  The ONLY U.S. seller who was selling it was asking $39.95!

You can get Fish Tapes, which is praziquantel marketed for aquarium fish. You just need to get the dosage right.
