Your Tigger is so wonderful!  We're so glad that she's got more bounce :) and that the visit to the vet went well.  You are a really good person to let your ex visit with Tigger, so glad she enjoyed it.  We hope and pray that you get good news from the surgeon; it's good that she will tell it to you straight.  We're lucky that way with our vet.adhjk;=7  I was going to erase that as Griselda just walked across the keyboard but I'll leave it in as her message to Tigger lol.

Whatever you decide to do, know that we support you.  Love and hugs to you, Tigger et al.
