Thanks, Matthew. Have been a little wary of giving him the brine in
which his tuna comes because of its saltiness. Have assumed that the
salt would not be good for him. He gets a little tuna every morning in
which are mixed his crushed medication (the furosemide and the
ace-inhibitor) but I have been seiving the tuna flakes out and trying
not to give him the brine. Maybe I shouldn't worry about this. Perhaps
the sodium will help make up for the electrolytes he's losing because of
the action of the furosemide?

We've had another beautiful day today and it's such a privilege to be
outside in the garden with him watching him rolling around on his back
in a state of bliss just loving it all. It's really weird to be
watching him, now seemingly restored to near-perfect health and
appearances, but knowing that inside his little body is an enlarged
diseased heart that we are told will definitely not last more than a
couple of years, if that.

Eddy.
