Hello and welcome. I think there is another breeder in Devon. Maybe join the Southern Hamster club and you may get some networking of other breeders through that. Or host a show in Devon maybe
I think there does tend to be an element of travelling with hamster shows as people go to the nearest location - for example there are 2 or 3 shows in the north of england but all are a bit of travelling for me in the north of england. Cornwall and Devon are quite a long distance I know - for travelling anywhere else. Whereabouts are you?
