At 10 weeks old the first vet told us to not give in and he would eventually eat. A week later we called back and informed the vet that his food had been sitting on the table untouched for the whole 7 days. That resulted in an immediate follow-up visit where the testing started.

One and a half years later, his team of top nation wide vet specialists have run dozens of tests and don't have an answer. He does make for good Lemmy OC content though :D
