Our 9 y/o rescue cat has not been eating well for several days. He had a vet visit and got a couple of shots Monday and moped around for a while. His energy seems back, but he is still congested and sneezing. The of thing is I put his bowl on the front porch and he gobbled it up. But moving it back in it's normal position in the horse, he was back to sniffing and walking off. Back out on the porch, he's eating. Any thoughts?
