In general, I'm not overly fussy about what the pet waiters/ staff wear, but I think heels may be pushing it slightly. Beyond the fact that a lot of the pets would have to shift between four legs and then perched on two high heels, making them clumsier, I'm not quite sure they'd fit the pet image. Tags, collars etc I think fit, as they're ID that pets would wear normally, but heels.. meh, I wouldn't mind too much either way.
