Pellets

I feed my rabbits on a diet of Burgess food pellets, hay and then bits of fruit and veg, mainly left overs but will give them the odd carrot or bit of lettuce if there is no left overs.

All my rabbits from the past have been fed like this and have lived for what i believe to be a good period of time and I have never had any issues, but i keep reading in paces not to feed them tomatoes because of this or dont feed them bananas because of that.
The only problem I had with feed was when I ran out over a bank holiday so my mum bought something from tesco and it gave my rabbit wind hahaha so i never fed them that again.

Is this right, or should i stick with what I find to be successful

I use this as a basic guide
