I have been having the same problem looking for the moist ones.  I
have 2 Burmese and one is very finicky.  I have tried all treats and
that is the only one she eats.  I called Purina and they said they
have discontinued them.  I live in the northern IL area and have tried
all stores around and in WI with no luck.
If I find them I'll write.

Thanks for your input, Matthew and Cybercat. If you see the crunchy
kind at a specific store, please let me know which one and I'll try to
buy them via mail order. My little old cat loves them so much that I
would like to buy a large supply so that he can enjoy them as long as
he can.

To give you further info, I contacted Purina a couple of months ago.
They told me they're still being manufactured and gave me the list of
Dallas-area retailers that carry Aquari-Yums, which included Petsmart,
Wal-Mart, and grocers Albertson's, Tom Thumb, Kroger, etc. Since then,
the product has dissappeard off of all of these store's shelves.
That's why I tried ordering online, but Amazon.com, Petsmart.com and
other online sites are all out of stock.
Thx!
