I've seen my cats bite each other, and after some research, I found that it was the cat claiming dominance (letting the other cat know "I'm the Alpha").
What surprised me was that one of my cats (named Fearless) started doing it to his mom, and the mother (named Booboo) didn't like it at all. It hasn't broken out into huge fights (yet), but the two seem eager to show who's the Alpha. Fearless is about 9 months old now, if that makes a difference. The mother cat is around 6 years old.
Should I prevent the offspring from claiming dominance in this situation? Is it a bad thing for the offspring to be the dominant one? In our world, the offspring showing dominance would be frowned upon, but the cat world seems to have some exceptions.
Some other details about home-life for my cats (which relate to this situation): The mother cat has another offspring (named Fatty (not actually fat though)) that doesn't do this, although it seems as if Fatty is starting to hop on the bandwagon by giving the mother difficulties during bath time (which hasn't happened since Fearless decided to start showing dominance towards Booboo). Fatty and Fearless are from the same litter. If both were to show dominance over the mother, would this trigger some emotional effect and make the mother depressed? (This is more of a bonus question; would be nice to get the answer, but answering the main question alone is good enough for best answer.)
