I have an idea of what the formula might be, but there are some exceptions. If anybody could help out, it would be nice.

For most pets, at my current CLs, XP gained appears to be 200 +/- 20 per level difference in CL. Exceptions are the rock beetle (130 +/- 13) and not-fully-grown creatures. Of course, I still don't know about the XP caps, nor about higher level creatures except by extrapolation...
