Also, on the matter of de-flea-ing, Stronghold in the same spot on pippettes as Frontline is also really good, with the added bonus that it tackles (cant remember which) worms too. Especially good if you have indoor cats that aren't keen on tablets (I say indoor cats as they are less likely to get the worse worm types - if that makes any sense whatsoever lol).
Finally, just last week I picked up some Bob Martin Spot on Dewormer from Pets at Home (or whatever Pet City/Pet World is called these days). available without prescription - again, a bonus as its spot on instead of tablets.
Have to admit that I have only skimmed this thread but this is what I have learned about flea control
1) Frontline works but is not enough if you have lots of fleas in the house, I found this out coming back from a week away to find the house literally jumping. Frontline wasn't enough but is good if you're using it for prevention or beginnings of an 'attack'.
If your house is infested too then the only thing you can do is to use a product such as Acclaim or Staykill in the home too, otherwise they'll continue to live and breed in your carpets/soft furnishing etc and no amount of flea treatments on your cats/dogs will get rid of them.
You're fighting a losing battle just trying to treat the pets
Edit: BTW, Advantage is another dropper type treatment, not an injection, and again is only available from your vet. I'm not aware of an injectable flea control, unless it's a very recent product on the market, and the only one that used to be available that "sterilised" fleas rather than kill them was Programme, which you put in the animal's food.
Yes - it is called Program and you can buy it to add to food but it is available as an injection for cats - at a price of course. We used it for our kittens when we got them and I think it was about £25 each but it was the year after our flea infestation and I was paranoid! It doesn't work outmuch more expensive than Frontline because it lasts (I think) six months.
This first-time buyer wants your thoughts
