A: No

B: Yes

C: Why is this a test?

I support A and B. The books haven't supported a death of Barley, but he seemed on the early adult side when he saved Bluestar, Tigerclaw (at the time), Ravenpaw, Graypaw, and Firepaw. Barley outlived Ravenpaw, who died at 8 years old of liver cancer. Barley is also currently alive at Hawkwing's Journey, but how old is this cat?!?!? Note this. Graystripe is currently 10.4 years old and isn't swift. Barley, on the other side, seems perfectly fine, taking care of Cloudmist and Cherrytail! Yes, his barn is packed full with mice but still?! Is he using five hour energy?!?
