This might seem totally weird to ask but...
Lets say you were feeding your hamster Harry Hamster Feed but you wanted to change it to Happy Hammy Food, would you one day give 3quarters old feed 1quarter new feed then the next day 2quarters old 2quarters new then 1quarter old 3quarters new then finally all new feed??? I have to do this with the horses I work with or they become very ill! Is it the same with hamsters???
