Daedalus is home! They called this morning and said he had responded well to the IV fluids and the muscle relaxers, and they actually had to give him less than they thought because he didn't have any tremors or issues after midnight. Thank goodness! We picked him up this morning and he hid under the bed for a little while but within a couple of hours he was back to roaming around the house. He's a little weak but got up on the kitchen table to beg for food while I was feeding Punk so it's nice to know his personality is still in tact. ;)
The vet who wrote out his discharge papers wrote in the papers that it was pyrethrine (or whatever) toxicity and that it was caused by the Hartz product. We didn't even have to ask her to do this, it was all printed out for us when we got there. I will definitely be calling them tomorrow and finding out where to send it so I can give them an earful. Also, because he didn't require as much medication as they thought, it actually cost less than their "low quote" (which I paid up front) and we ended up getting a $70 refund to my credit card.
I am really pleased with this emergency vet hospital. They were really awesome.
In his discharge paperwork, it mentioned that he had a very sweet personality. Oh yeah, that's my big loverboy.
