Yes, it can. All herbivore manures are good for composting. Just remember to get the pile hot enough
to kill any seeds.

And contrary to another post, human, dog, cat, pig, etc., can be composted.
However, DO NOT use these materials in your compost pile. Most piles don't get hot enough
to kill any disease organisms. These manures require special handling. See the following:

And many, many more, just use your favorite search engine.
human manure compost -- replace human with dog, etc.

Remember, ALL manures can and probably do contain disease organisms.
E. Coli, salmonella, parasitic worms, etc., etc., etc. -- Handle accordingly!! --
These manures (after composting), should probably be limited to use on your trees, shrubs, etc.
Also, you can setup a worm bed for composting these manures.

How do you keep your cat(s) out of your garden? They just love 'soft' turned soil to do their business, so much easier to dig in.
