I'm so sorry for Pouncer , but glad that you used your own good sense
and gave him pain meds. I also doubt that he'll start suddenly feeling so much better as to be bouncing off the walls with happiness. He hurts to much for that. I used to use an old puppy crate(never used) to separate
any cat with injuries while they healed. It worked great when then had to
separate & quieter for awhile. I do hope your mom heals quickly also.
