Anyone know how long it takes for the drontal to work? I just woke up this morning and found that someone threw up last nights dinner again...no worms in it though, but I'm still concerned about this vomit. I wish I had surveillance cameras in the house to catch whoever's doing this!!!
I'm not sure but I've heard that some cats will get an upset stomach and throw up if the drontal is given to them on an empty stomach.

When my Sky had tapeworms, he was given 2 drontal pills at the vets and then I had to give him 2 more pills 3 weeks later to be sure that the worms were dead. I gave him his pills after he had eaten his breakfast and everything went well except that he almost bit my finger off.

I'm sure that all of your furkids will be just fine. Good luck and take care.
