Oooh. You went on to talk about his attitude. Yup. You've nailed it. He's just in pain so he's grumpy. He and I are oddly familiar, temperamentally. Thankfully for him he's more front wheel drive. 😂 As you were walking with him and pointing out his movement I looked at the imagined weight of his head and thought, "Good thing he's FWD with those back leg problems." At least when he's not walking, that is. It's not likely anything would be safe but any chance you could heat an area for bobcat to sleep on? It helps with the pain. It's easier to get up and start moving in the morning, I can attest. I can't imagine what could be a safe bed warmer for a lion except for building an enclosure like Koreans built their homes so fire goes under it and out the chimney on the other side, warms the stone and keeps it warm for a surprisingly long time after. If they could build it so entire houses stayed intact on top of it, two lions could as well.
