Yes you can. I find those rabbit pellets all over my yard all the time. However you can extend the use of them by composting them first.

Rabbit poop is one of the highest manures in nitrogen, and it also contains a large amount of phosphorus--important for flower and fruit formation.

I get rabbit poop from a girl who breeds bunnies to show competitively. She lines their catch trays with peat moss.

She's tried everything -- wood shavings, petstore bedding, newspaper, shredded cardboard -- and peat moss works the best for odor control.

Rabbit manure N-P-K numbers are 2.4, 1.4 and 0.60

If you want to learn more about composting, Mike McGrath's Book of Compost is a good starting point and a humorous read. He also has a good chapter on compost for lawns.
