Are shop bought flea killers any good?

You shouldnt put flea things on a kitten so go to the vet and they will get you all you need

The shop bought stuff is terrible. My guess is the kitten will also have worms if it has fleas.

Get a glass of water and when you see a flea, take it off the kitty between your finger nails and with your fingers clenched, drop the flea right into the water. That way they will drown and its one less flea to lay eggs on your floors and one less to bit the kitten.

I did think he may be a bit young.

Thanks very much, will ring the vet tomorrow
