Mr Miyagi is home. He's clean as a whistle - literally! The third enema took care of the rest and xray showed he's empty.
I wasn't there when hubby went to pick him up, but he did speak to the vet about our choice of going with a LID canned food, as opposed to the HP dry food she was suggesting. He also mentioned the use of olive oil, slippery elm bark, etc to help with any future constipation - she said a lot of that stuff is really a myth (which is ridiculous in my opinion, but whatever). At the end of the day, she said it's completely our decision but to just let her know what we've decided so she can make a note of it in his file.
We'll go back in 2 weeks so she can re-examine him and make sure he's still doing alright.
