do i need to max both fusing pets to hit max level?
You don't have to, if you are just going for the sprite but if you want your pet to be good, then always max both before fusing.
Also remember to keep the pet you want to keep the stats on on the left side when fusing, because the one on the right disappears after you fuse them.
