Ok thank you. I will stop with the mange tout.
I don’t give much more than a tablespoon of pellets each time, I just measure it with my hand. I have been cautious with suddenly reducing the quantity of pellets as at the rescue they just had a big bin of different types mixed together (whatever had been donated) and they got a decent scoop.
I will increase her cystease then if that is ok to do.
Never worry about being cautious reducing pellets - they are the one part of the diet they actually don’t need at all and if they are being over fed the best thing you can do is reduce them.
Because most calcium comes into the diet via pellets there is never any benefit (only risks) with to giving more than necessary
