Well, hurrah!
Did you see our discussion about your dear Henry on other thread? I think Joanna's idea is very interesting. If Henry is getting this long duration in the daytime and is too low to shoot at +12, wait until he is in the 200 range (even if it is +15 or so) Shoot what you would regularly do at that number. Our thinking is that might reduce your amps? If your amps is in the 200 range (even at +9) and definitely rising -that would be the part to be careful about - then shoot that number in the morning. What do you think?
Of course, if this discussion works like our other ones about the kitties here, he will just change on his own.....They seem to hear us talking and make a turn around!
