Well, our day did not end as expected. There were some anomalies in our cats' bloodwork, which require a follow-up in 14 days. After chatting with our vet, they went to remove the catheters from our cats (they got fluids all day that way). Our younger cat was cool with this; our older one, not so much. He bit one of the vet's assistants. So now that has to be reported to animal control (shouldn't be too bad - they won't require he be put down or anything); and it took over an hour to retrieve our cats because he had to be sedated to have his catheter removed. In short: these two cats had a long ass day and I just want them to get some rest. They've earned it.
