We are back home from another round of vet visits. Last night, I wasn't sure if I needed to take Tenzing to the vet again, but this morning, after a rough night for everyone concerned, I was sure. He's normally grateful when I (finally!) go to bed each night, and sleeps contentedly on my knees, but last night was different. Through the night last night, he woke me every 1.5 - 2 hours, needing to be held and comforted.
This wasn't Tenzing.
