Hi everyone been a lurker for a while but never posted so please forgive me if i say the wrong thing!!

Rosie is an 11month old ruby and she is perfectly healthy and naughty but she's tiny!! i weighed her last night and she weighs 5 1/2 lb which seems way too tiny compared to most of the results i have found by googling!! any advice or shared experience would be gratefully received. Vicky
