As you can see celery contains a little sodium, phosphorus, calcium, quite a bit of acid, a hint of fat and a little sugar.
They can eat celery and they make a nice addition to their diet and supplement hay quite nicely, just chop it up into pieces and feed three to four times a week at the most. A few pieces a day should suffice.
Just don’t give them too much at any one time as too much may upset their tummies.
