Oh, me too. Standard dose for humans is apparently ~7-30 mCi and they usually go home the same day. Cats get ~2-4 mCi (Ariel got 1.5) and have to stay at the vet for 4 days or so, then 2 weeks of minimal contact, etc. It doesn't really make sense. (I borrowed a Geiger counter from the lab, though, and she's definitely well above background levels! I also read that cats go home when they do partly to minimize exposure for the vets and staff who work with them- better for each family to have a little bit of exposure than for the vets to have even more than they're already getting.)
