So today I gave my piggies some carrots and lettuce. I think they may have had to much because spikes poohs look a little mushy or is that normal because I am just starting to give them veggies. I didn't intend for them to eat a whole bunch but I think they may have had alot. How should I go about introducing veggies to them so they don't get sick or get tummy aches or what ever.
