Growing grass for your rabbit

I just bought a box of cheap grass seeds from asda and some compost to grow some grass indoors for Rocky, but a friend as since told me that she wasn't sure, but she'd thought some grass seeds weren't suitable to use?

Anyone know of any probs with doing this? I think I read someone on here doing it before, might have been Indiechic??

ooh thanks! I never thought to check there

Planted and watered. Fingers crossed! (I'm not very good at gardening/growing malarky)
