just reading the weight by age chart, how big in grams do average males grow to? monty is 450g, but I think ive been feeding him too smaller rats! so have now got him some bigger rats
The more you feed them the quicker they grow BUT and as you can see its a big but its not a good idea to over feed to make them grow faster. I think they get to where they are going eventually but when they get there slower its better built so less likely to go wrong.
