Guinea pig ate a daisy

Question
I gave my 6 year old male guinea pig some grass to eat, I didn't realize until after that the grass contained a daisy and before I could remove it he ate the daisy. I researched on the Internet and apparently daisies are toxic to guinea pigs, it was only a small daisy, will he be okay?

Answer
he should be okay, most flowers are toxic to guinea pigs but as you say a daisy is only small and i would be very surprised if guinea pigs have not eaten scores of them while grazing on the owners lawn, but keep an eye on him and if he seems to be taking a turn for the worst then get him to the vets pronto.
