The easily used FHL Archives at
http://ferrethealth.org/archive/
is what you both need. For the bladder diverticulum search for
messages that contain Hilbert. (There might be some others w Hilly
or Billy-Bert.) Of course, also search for diverticulum in posts.

For the enlarged hearts you are seeking info on dilative
cardiomyopathy, also called hyperplastic cardiomyopathy. A compilation
of old posts can be found in the Files section of the FHL
http://pets.groups.yahoo.com/group/ferrethealth/
with more recent posts in the archives (addy earlier in this post)
such as:

>For ferrets with dilated cardiomyopathy a few things are recommended.
>An ACE inhibitor such as benazepril or enalapril (Enacard), a diuretic
>like furosemide (lasix), and a medication to increase the strength of
>the heart contraction such as Vetmedin (pimobendan) or Digoxin. As far
>as doses for ferrets with benazepril a dose of 0.25 mg to 0.5 mg/kg
>every other day to once a day. For furosemide a dose of 1 to 4 mg/kg 2
>to 3 times a day. For Vetmedin a dose of 0.2 to 0.3 mg/kg 2 times a
>day. It sounds like your little guy is getting too much of the

>Side effects are uncommon but can include: increased drinking,

>Higher doses can induce sinus tachycardia (fast heart rate), and
>ventricular arrhythmias. In an article on Pimobendan use in more than
>100 dogs (U of Georgia), found Pimobendan to be "virtually free of
>overt adverse effects in dogs..." One dog did develop mild diarrhea.
>Thus less than 1% developed mild diarrhea. That is a lot safer than

>When Pimobendan becomes approved here in the US, it will be become

>moderate to severe dilated cardiomyopathy cases.
