Have you tried asking your vet? I did and it turned out that one of
the nurses at the practice runs a little business "on the side" as a
pet sitter. She not only feeds the cats and changes litter, but plays
with, cuddles and brushes Lucy. Tia, of course, hides in her bolt hole
under my bed while she's here as she's a bit shy.

It's not a cheap service, $20 per day, but it's worth it for the peace
of mind. Oh, and Alison will also put the bin and recycling out for
collection if I ask her.

Cheers
