[Stones] CARE: feeding bell peppers

[Cindy]

I have a question about feeding bell peppers.  I stopped feeding the 
green ones after discovering Sunshine's bladder stones; however, I 
thought that the red ones were supposed to be OK.  A friend of mine, 
though, said that bell peppers are a solanaceous herb and can contribute 
to stone formation.

It seems, then, that there is no difference between the red and green? 

Help!

TIA,
Cindy
