Onyx is a big, 11-year-old boy who needs to be rehomed because he has recently been triggered to fight with his brother, causing a special-needs family member to become upset. When not fighting, they are always together, but Onyx is the aggressor when they fight.

Onyx is active and likes to play with toys. He enjoys drinking out of the faucet and likes to spread out on the floor, showing off his magnificence!

Onyx has not been around dogs and the only cat he has been around is his brother.
