Sorry...

Dad took Simba to the vet while I was at school today. ( after begging him for two days. ) He called the Vet first, asking them about it. They said it was from his vaccination ( I would have freakin known if dad told me he got a shot there, instead of worrying my butt off!! )

Anyways, He's fine, thankfully. Vet says it shoulkd go away in a few months.
