Following any kind of philosophy requires some level of autonomy and ability to recognize one's right to self-determination, which I don't think translates well to pets. Does imposing one's own philosophy-based diet on another autonomous, but controlled organism imply some kind of cruelty? We also apparently neuter pets "for their safety". The whole idea of pets is inconsistent with veganism anyways, so I am unsurprised that there is more dissonance in the conversation.
