Nice to see Sox is making progress - even if your sis didn't feel comfy shooting tonight, overall, he's doing great.
I saw your other post asking about reducing his dose while your sis is gone. I don't understand if he's going to be tested or not - is he?
I'm raising the question because sometimes when a cat begins to make progress it can be fast. Your sis had to skip a shot yesterday morning and again tonight - that was a very fast recovery after a skipped shot. Can your sister teach her daughter to test Sox before she goes?
By the way, next time, you can just change your subject line to reflect any questions that come up during the day instead of opening a new post - that way all that conversation about the vacation dose and this post would be all in one spot.
