We decided to give him another 24-hours of hospital care so he could get lots more fluids.
When I visited him this evening, the vet tech said he was doing better, eating about half the food they were giving him. He seemed more perky than last night, which is a good sign. Current plan is to check in with vet first thing Wednesday morning and hopefully bring him home before work.
Meanwhile, in Marvin's absence, the other kitties are re-occupying the upstairs! They all slept with me last night, even Rose was nearby. What a delight to get to share the bed with them again.
They all miss their upstairs territory, which they had access to before Marvin came on the scene. It's sad they can't share the space with Marvin (he's very territorial).
Theo so loves the spot on top of the cat tree!
Thanks everyone for your prayers and purrs!
