I'm sure you know that guilt is a normal part of the grieving process and we all feel like we could have done better when our little furries leave us for the rainbow bridge ( oh boy, about to start crying now, only lost Mr M a few weeks back ). No matter what you did or didn't do in your eyes you'd always feel guilty, we miss them so much we always wish we'd done more for them - know that you did your best, he was loved and loved you back.
