I have 110/110/100 and have stable slots (that's 10 total) to spare.
My pets I use are: 2 bake, 1 rune beetle, 1 greater dragon, 1 cu sidhe and 1 reptalon (untrained). The other 4 slots go toward pets I plan on giving away, mostly fire beetles and pack beetles, but if I find a good rune beetle or cu, I'll tame those for giving away too.
I'm thinking about upping all my skills just so I can make (and keep) a pack of hell hounds. But then I'd need to stop spending all my gold on silly things like armor for the "new" guy I just met.
