So sorry to hear Cricket is crossing to the bridge. I had both Tidge and Bramble PTS with a sedative first. I have had good and bad experiences with sedatives before the pts injection but even so I would never pts without giving a sedative first. What I've found is that even if they have a reaction to the sedative they are less likely to be aware than they would be without the sedative.
Prayers for Cricket that he will have a peaceful and quick passing. It's never easy but at times like this when you know in your heart they are suffering with no hope of improvement then I feel it is the kindest thing to do. Cricket knows he was loved and cared for and you gave him every chance in life. Having someone to drive you home afterwards is always a good thing. Michelle, Buddy, Minstrel & Angel Bramble
