Yesterday I got C.B. back from his second round of radiation treatments. They worked very well last time. He looks worse again now and has more discharge from his eye and nostril, so I'm looking forward to it taking affect and making him more comfortable. C.B.'s vision is obviously very impaired, possibly from the first radiation and/or the tumor itself. I think he can see light and shade and maybe shapes. He's pretty energetic, though, and seems to use touch, smell, memory and echolocation, which would explain all the loud meowing. All in all, he seems to be fairly tough considering everything, including being 18, and is as affectionate as ever!
