Whitey still wasn't eating this morning, so back to the vet he went. They said he's becoming dehydrated (uh oh), gave him subcutaneous fluids, a prescription for Pepcid to settle his stomach, and instructions to come back again tomorrow if he still isn't eating.
On the way to the drugstore, I remembered that the vet suggested meat-flavored baby food as an alternative when Emily was sick. So I got some. Whitey rejected the portion that I spiked with Pepcid, but otherwise wolfed down almost the whole jar. Yay!
Of course, if he's really channeling his aunt, he will now refuse to eat anything other than baby food. Sigh...
As a side note, he is (not surprisingly) becoming extremely suspicious of his carrier. I had to get out the ShrimpNip to persuade him to get in it this morning. ShrimpNip is essentially crack for kittens: dried shrimp tossed with catnip. It stinks to high heaven, but overcomes almost all feline stubbornness.
