Thank you, @BJM - I ordered Canna Companion today. They don't guarantee anything, but at this point, if I didn't have the hope of that, and Eegie doesn't improve tomorrow (I get the canna on Thursday), tomorrow would be Eegie's last day. He's been unable to walk and is very ill. Earlier today it wasn't as bad, but it's progressed. It did occur to me that perhaps the lasix for his breathing has caused him to be dehydrated, so I'm upping his sub-q and cutting the lasix until I can talk to the doctor (this only occurred to me at about 7pm today). But, Canna's my last hope and I'm afraid I'm going to take it. I'd gotten no responses here all day, but got many positive responses on several of the other forums on which I'd asked.
Thanks for getting back to me on this...
