The best compliment you can give squirrel is that it doesn't taste like squirrel. Keep that in mind. Have fun cleaning 'em. They can be really agravating.
First comment. What is the point of eating squirrel if you want to try to mask the taste because you don't like it? I mean, if you want it to taste like beef (which, obviously you do since you added beef bouilon cubes to it) then why not just add a little beef to it? I know the economy is bad... but beef isn't THAT high.
Secondly, squirrels are super easy to clean, if you use the right method. Just cut through the base of the tail and peel it up along the spine towards the front arms, pull the front arms through and pull it all the way over the head, and cut the neck (completely through). Then, peel off the remaining fur on the back legs in a similar fashion. Only takes 2 minutes or so to do by yourself, at most.
