As you can see celtuce contains quite a bit of phosphorus, a little calcium, quite a bit of acidic content, and a hint of fat and fibre. However they do contain quite a bit of water which can cause bloat.
This means that rabbits can eat celtuce but not too much as it will hurt them if they eat too much.
