Uh...you just lost me, Mr. Cutter. ?
Extinction Kit? Really? I've been in the vet field for 22 years, and I've never once heard of Euthasol being packaged this way. And, perhaps a little research on dosing of Euthasol would have been a good thing. While 2.5cc is certainly more than enough for a Guinea Pig, it's definitely not enough to "flatline a Great Dane." #factcheck
Inaccurate information like this just completely rips me out of a story.
