I never read up on that part...lol...hopefully someone else will have the answer.

Droncit is a spot on non prescription wormer to be applied every 3 months. However it only tackles Tapeworms.

Profender is a spot on Presription Only Wormer to be applied every three months that tackles Roundworm and Tapeworm.

Stronghold and Advocate are spot on flea treatments that also tackle Roundworm. They are to be applied monthly. They are prescription only and DO NOT protect against tapeworm.

All availiable at Pet Drugs Online For prescription only products your vet is legally obliged to provide a prescription if requested. They will charge but will give you a prescription (if you ask) that will last until the cats next check up usually 6 months or 1 year.

If your cat is a hunter or scavenger you should treat more regularly with droncit or profender but the standard is three month intervals

Thank you very much for all that information....very much appreciated.

Hi.

Can I just ask someone to elaborate on the Bob Martin stuff being noxious please? I have recently used this, and am now worried about my two. They seem ok, but I have noticed the area where I applied it smells like poo it's disgusting!! I won't be using it again for that very reason. I will probably ask the vet to sell me whatever he used to use on them in the past. Yerch, horrible Bob Martin stuff!

RE- BOB MARTINS- as long as you use it correctly it should cause no problems. The issue happens when people use dog wormer on cats- happens frequestly when people are trying to cut corners and save money. The dog bob martins is extremely toxic to cats, has warnings all over the pack, and I have seen cats bought into the surgery within an hour of application having serious fits. Luckily the few i've seen did survive because they were bought in in time.

However bob martins is not a veterinary product and does not need to comply to the same regulations. It is therefore not as effective so combined with the risk of toxic poisoning it is best to use a veterinary wormer.

If you want a spot on treatment use one of the ones I suggested earlier which are all veterinary products.
