No, not from a ragdoll breeder, but a friend of mine who shows and breeds Ridgebacks (my breed too, though I don't breed them) He is a raw feeder and not a fan of vaccinating, and reads a lot of "natural" articles online, most of which are usually absolute rubbish, and I said I had certainly never heard of this but thought I should check before I 100% rubbished his claims :) Thanks everyone. I will continue to look for articles, and if I find any, then I shall post them on here.

I've had a little google and found this report of a study http://www.ncbi.nlm.nih.gov/pubmed/15328714

It was specifically looking at the risk in transitional cell carcinomas in Scottish Terriers and the conclusion was that they did NOT find a link with topical flea treatments. I can't find anything else really, except one reference Oncology for Veterinary Technicians and Nurses - Page 11 which refers to a link with other pesticides, but specifically not with topical flea treatments - referring to the earlier study I think. I did also find something saying that spot-ons were preferable for Scotties, but I can't find it now.

It seems to me that perhaps someone has got the wrong end of the research that's been done. It's easy for rumours to spread, but I can't find anything to back this up. Can anyone else?

Can I just ask if this came from a breeder - specifically a breeder of ragdolls. It has been discussed on one of the breeder forums but I haven't read anything to support this claim yet

I've never heard of this. I've heard of cats getting injection site tumours and such but never heard of spot ons causing them. Would be interested to read any papers if there are some.
