I am so sorry to hear of Dear Toby.....this is so difficult a time for you and his pet humans!!!
but please encourage them that they did the right thing....there are many caring sites out there you can visit to help with the grief...petloss.com,rainbowbridge.com...petlosssup port,etc.
just please remember that Toby has many,many friends at The Bridge with him who will care for him till you can be with him again...He will wait for you!!!!
my heart goes out to you....
My Dear Scrubber is up at The Bridge waiting to care and play with Toby as we speak....

Dear Toby....have a safe journey to The Rainbow Bridge...
You are at Peace now
and Loved as Always
