Actually, with monster reflavoring, you could easily make a 'cat' stat block out of pretty much any stat block you felt like.3e, for all its flawed philosophy of "a stat for everything!" wound up less than ideal, did not disappoint me in this regard. 4e, with its philosophy of "Figure out what is for combat, and what is for not-combat, and here's the combat things, and the not-combat things don't matter," was a lot more problematic for my playstyle.
Monster creation was dramatically easier in 4E than it was in any prior edition, hence me never really worrying about things not being statted. Only solos were in any way difficult to make. And that is as it should be.
