Thanks for sharing your lovely ADC's from Rusty with us and with your doubting friend, Don. I and many others also believe our sweet pets have a soul and may leave this plane, but we will see them again.
If God, their Creator, says He knows how many hairs are on our heads (ie. He is aware of everything about us), and He says He even knows when a sparrow falls, then He knows all about Rusty the kitty cat. Those ADC's show me and others that our pets live on in another plane, just like we will do someday. :)
Indeed, Heaven won't be Heaven without our precious fur babies!
And, yes, God IS so good!
