Feeding too much

Question
When I first got my Guinea Pig she didn't eat to much hay and not a lot of pellets so I was feeding her a small handful of shredded lettuce or spinach a baby carrot and either a piece of cucumber or green pepper twice a day.  Now she is eating a lot more hay and pellets should I be giving her less veggies (like maybe cut out the lettuce twice a day since there is no vitamin c in it)?  I don't want to overfeed her.  

If you don't have a scale how can you tell if they are getting fat?

Please help I don't want to kill my GP!!

Hi Rebecca

I think you are right. Lettuce has almost no  dietary benefit for your pig anyway, so you should only give this as a treat.

I think a good diet is pellets for breakfast and veggies for dinner way hay and fresh water available at all times.

A fat piggy isnt too much of a problem but well done for being so proactive to make sure she is as healthy as possible.
