...and his familiar, Tonto

It came up in chat how much you could boost a familiar. For your run-of-the-mill familiar it goes as following:
Natural poundage (20) + Familiar Equipment (5) + Amphibian Sympathy (5) + Empathy&Leash (10) + Green Snowcone (5) + Heavy Petting (5) + Plexiglass Pith Helmet (5) + 3 Tiny Plastic Familiars (3).

For a grand total of: 58!

Those without boosting familiar equipment will have 5 less. The Pet Rock will have 6 more (its familiar equipment gives +11), and the Doppleshifter can be boosted to 68 (+15 familiar equipment).
