I’ve also had great success with the medical manuka honey. This was a huge abscess on my Guineas jaw which was stitched open to heal properly. I had to flush like you are but then I squeezed the honey in after. I was very impressed with it.I did think about it when he first had the surgery (as great with Sheepy my old piggy on his nasty one years ago) but got a bit worried he may get a taste for it! They can't really have much sugar.
Will ask Simon when I call though and see what he thinks. Got naughty 3yr old nephew causing havoc and lots of noise atm!
Thanks, he's eaten a little mashed pellets overnight and time for feed and flush soon, may have to tie the 3yr old up for that! xx
