I took Seby back to the vet today. He's still in pain.
We took x-rays. They show a possible kidney stone, arthritis in his lower spine and a very enlarged heart.
They drew blood and urine for testing and gave him some pain pills. I'm dropping him off tomorrow for a whole day of observation. The vet wants to see if they can observe what is hurting him.
I will not panic, I will not panic, I will not panic...
