Is there is an effective flea/worming treatment in the UK that can be bought online without prescription. My vet is charging £22 for one prescription and we need one for each of our kittens (well they are 9 months old now and starting to venture out). I know the shelter said Bob Martin/Frontline are rubbish and not to bother. Interesting that Chillminx said Fipronil doesn't work is some areas in the UK, I am guessing that is what is in Frontline. We are in Yorkshire. Thank you for any recommendations. (Note: one of our cats has a very sensitive stomach, possible IBD).
