Bob Clark though the same thing with his Leusistic Burmese and she never did reproduce...he chalked it up to the Morph must make it infertile....yet now they produce them....
Same thing was said about Caramel BPs...like I stated to many large breeders are working with them and soon info will be posted on the secret to breeding them. I would be willing to say its a temp thing.

Bob's leucy was later diagnosed with pseudamonas, which at the time was rampant throughout many burm collections in the US.
