worms :/ plz help!

 So Oliver seen the vet a week ago and got a clean bill of health and some de wormer. He got a pill a week ago and he's supposed to get his second pill in another week and then in another 3 weeks... My problem is that he has been picking at his bum a lot! I know they're still there and bothering him but he's been awful gassy too. He's gassy and tonight (like 10 minutes ago) we were on the bed and rolled over and I noticed a lump on his bum. It turned out to be poop stuck there so I managed to trick him into getting rolled up in the sheet and I wiped it clean. The poop DID contain tiny itty bity dots (worms for sure)..

  SO 

What can I do to help relieve the discomfort for him and the poop and gas for us?!?

So he can poop (bc I just watched him) but he hissed at me for the first time just then. I was playing with him and then I gave him treats and put some dry food down and he got weird. I think he has some discomfort in his belly-though he lets me touch him. What can I do?

I wish I could help, but I have no experience which this issue. If he was just recently treated at the vet, you could try to give them a call there and see if they can provide any guidance. Vibes for your kitty 

It would help a lot if we knew what dewormer he was given. If a pill, it's usually either drontal or droncit. Drontal is supposed to treat both round worm and tapeworm, if I recall correctly. Droncit I know treats only tapeworm. Unfortunately, if he has round worm, drontal is not always effective. Where we live, the round worms are resistant, so it's useless.

I'm sorry, I don't know Oliver's background. Is this a rescue kitty? Or is he indoor/outdoor?

Either way, does he currently have fleas? Or have those been treated, and they're no longer a problem?

We've found the most effective way to treat (most) internal parasites is Revolution - a topical treatment. It also treats fleas (and supposedly ticks, though it doesn't do a very good job on the ticks). When you've finished three cycles of treatments every three weeks, then give kitty Droncit to kill the tapeworm.

The round worm life cycle is such that you have to give treatments every three weeks. Most of the poisons used to kill them, whether Panacur (a liquid), Strongid-T (a liquid), Revolution (topical), Advantage Plus (topical), or Drontal (a pill, often not effective for round worm though its supposed to be), treat the adult round worm. So you have to then let remaining eggs mature, and kill those adults (2nd treatment). And to ensure you got them all, a 3rd treatment is usually given. Thus the three week spacing between treatments. You also need to be very diligent about scooping litter, so the cat doesn't get reinfested from its own feces.

I have to assume this is the issue, because tapeworm is (usually) resolved with one treatment. Tapeworm looks like little bits of rice. It can ONLY be transferred to a cat via a host, such as a flea bite or eating a mouse or something. However, if the cat still has fleas, or is allowed outside to hunt, the cat will continually have the problem with tapeworm. So if the first treatment didn't stop the tapeworm, he's getting reinfested somehow, and you need to figure out the source.

 He's rescued from a life of outdoors. He does not have fleas thankfully. http://www.thecatsite.com/t/238728/olivers-first-appt#post_3147121   This is the link for his vet visit. And the pill is there. It begins with an "M".. It gets rid of all worms. He's fine now. That incident lasted a night or two but he's fine now. He's due for his second pill on Dec 17 ^.^
