Thanks everyone for your prayers and purrs - it worked! My mom tells me that dad's procedure went well. He needed only one stent and got to come home the same day. So, now he's resting at home. Yea!!
Dad, I hope you feel better soon! I'm sure if you had a cat purring in your lap it would expedite the healing process. I would loan you one (or two) but the distance is great. Sadly, I don't think dog licks are nearly as effective a healing agent as cat purrs but I guess you'll have to make do.
I also really, really appreciated everyone's comments about the euthanizing of in utero kittens. I was feeling horrid about it and knowing that I'm not alone helps me a lot. Together we can grieve the loss and keep doing what we can to care for the community cats.
No new news on Willow. She continues to act normal (and wonderful!) I haven't been around to witness a poop event to know how that goes for her. Hopefully, I'll get that opportunity over the weekend - that sounds like a good time!
