We've had our Felix-style rescue cat, Mambo, for about 6 years now and we
were told he was around  4 when we brought him home. He's only notionally
male as he had the op prior to adoption.

When he first came to us he was a bit (not to put too fine a point on it!)
fat, weighing in at just over 20lbs - though he is quite big-boned. Now,
though he still weighs 15lbs, he's looking quite thin and bony except for
his pink bits which are a bit slack. As well as losing weight he is losing
fur around his haunches, and he yells for food every time someone moves - I
mean EVERY time! He even follows the dog downstairs hoping he's at last
learnt to operate the can-opener! You would think we are starving and
neglecting him but nothing could be further from the truth. He's always
liked his grub but has become increasingly demanding.

He eats around a tin of Whiskas plus biscuits a day. He's fed this in 3 or 4
sittings otherwise he will gorge himself and then throw up. He doesn't seem
to be scratching much at all or drinking excessively and the rest of his fur
is quite sleek. His eyes are clear and he doesn't appear overly stressed:
he's usually curled up near or on one of us, quite contented - he's not an
'out' cat.

My forearms are just starting to heal where I wormed him a couple of weeks
ago and I've not seen any evidence of fleas or worms.

Any of you experts out there any ideas please?

Thanks -

Lez
