Kate I wasn't online at all over the weekend and only now catching up. Please tell Gus I am so very sorry. Knowing when to let go is one of the greatest gifts we can give our pets and I hope Gus is able to let herself grieve. Hopefully also with time she (and you) will be able to look back and have fond memories vs sad ones.
(((hug)))) to you all
RIP sweet Ruby and play hard at the bridge
