in lieu of euthanasia...i.e. instead of euthanasia

I know what 'in lieu of' means...

I took that to mean methods of putting the animal down at home in lieu of vet-assisted euthanasia rather than alternate treatment. (Though I don't recommend anyone put an animal down themselves, it's not an uncommon suggestion on some of the exotics forums I'm on, so that's where the confusion came from).
