You have my deepest sympathies over the loss of your Joey.
No matter for how long we have had them, saying goodbye is never easy. Time will ease the grief and hopefully soon the memories of the good 10 years you had with Joey will give you comfort.
If despite the extra TLC given to your Sami, you notice he doesn't seem to be coping well and appears depressed, you may want to consider getting him a new same species friend.
Rest in peace, beautiful Joey. You were much loved and will be missed
And despite the very sad circumstances, welcome to the forums.
