Today i let bunny run in my backyard i made a circle with left over garden fences (she learned how to get out tho) i think she ate grass.. is that bad?
No eating grass is not bad, as long as it hasn't been treated with nasty pesticides etc.
In the wild grass makes up a large part of a rabbits diet. When my girls are out in the run they nibble grass, andI sometimes pick it for them if they are inside.
If she's not used to it, then it would be better to allow her tummy to settle, to see if it has any effect on her.Giving her more when you don't know how it might effect her is not that sensible, in my eyes.
Maybe youcould give her grass daily if you wanted to, especially if it doesn't give her diarrhoea.
