Dried blood should be available at your local garden store. It is a biproduct of cattle beef processing. It comes in a powdered form and is effective for discouraging deer and rabbits from eating your plants.
In a large bucket, combine dried blood and water until dried blood is disolved. Apply using a spray bottle or garden sprayer.
Caution: Use this solution sparingly. The nitrogen in the dried blood may burn your plants if it gets too concentrated. You can also try sprinkling a little dried blood mixed with bonemeal around threatened plants.

Received by email: The dried blood solution to repel rabbits, will that harm my dogs or cat in any way?
We don't believe so but it would be best to check the package and see if there are any pet warnings.
