Brady is feeling better and seems to be stabilizing.  His breathing has improved and he is actually purring again!  This is a very good sign!  Our vet says that his lungs sound much better and we are staying on the double dose of lasix from here on out.  Thanks again for all of your gifts, support, prayers and donations; we couldn't do this without you! 
 
Picture
Brady seems to be feeling a bit better, slowly but surely.  He is eating again and is now back to a healthy weight and his breathing is less labored as well.  Keeping our fingers crossed that we continue to see improvements!  <3  Vet wants us to have another echo done so we're saving up some money and planning on trying to get it done at Purdue where it's much cheaper...
