Hi i breed ragdoll cats and i usually let mine go at 8 weeks.By this time they are tearing round the house like loonies,eating well and hardly feeding of mum at all(maybe 5 mins here and there until mum gets fed up and gets up!)someone who has reserved one of my current litter bought her 1st one at 5 WEEKS ! she actually bought 2 but 1 died shortly after recieving its vaccinations...I dont vaccinate i leave it up to the new owners,but i do recomend killed vaccines only,if they do.However most vets say otherwise,and say its fine.I do think vaccinations are very overrated and on speaking to one very senior vet he told me that there is actually no need for yearly boosters and animals are actually covered for longer than you think...
