I discovered today that our barn cat Danny has been listening to the radio without my knowledge. I had to take him to the vet today because half his face was swollen, and he had a small abscess on his chin. During our 1 hour LONG car ride (round-trip), Danny sang-a-long to every song on the radio. I tested his knowledge by turning the radio off and he kept on singing!
Hopefully the antibiotic injection and 5 days strictly indoors will have Danny healed up.
