I think you should contact the veterinarian who prescribed this and ask. We don't actually allow dosing information to be dispenses here. It's simply too dangerous. Veterinarians - like doctors and pharmacists - not only know what the dosage should be, they should also be more familiar with common mistakes people make with doing and what the effects may be (which could affect the "Severity" of instructions).Hi, i have the 50mg/ml bottle of Pyrantel and wondered the correct dosage for 8 week old kittens, all are between 1.5 & 2 lbs each. Thanks!;-)
