definitely hay and my two have anything that's a leafy green really.
savoy cabbage
spring greens
curly kale
parsley
coriander
basil
thyme
lettuces - romaine, little gem, trio leaf
watercress, rocket, spinach, red chard mix
there's other veggies but i can't remember them at the minute. :roll:
then grass, dandelion, apple sticks etc.
and dried herbs, flavoured pellets and mixes from pampered piggies
and oxbow cavy cuisine but only a small amount at night
pampered piggies do some hay and other things crushed into pellet form. i know it won't help with the chewing motion but might be a way to give hay based foods? :wave:
