Hey everyone, I have a small problem with my cat Odin. Odin is a 17-year-old Norwegian Forest Cat. For about three weeks now, he won't let me brush him; he hisses at me as soon as I even pick up the brush! I've checked him for injuries and haven't found anything that would explain this behavior. Has anyone experienced this?
