Chondroitin sulfate

[XXDU78A@prodigy.com (MS LOUISE D BURTON)]

OK.  I bought three cans of CS to compare.  Here is the analysis for those
interested.  I would sure appreciate feedback from some of you more
knowledgeable people with regards to which is best.
Do some of these work and others not?  I have a cat on PET FLEX who is 16.
Amazing difference in her.  I never thought about her being arthritic; she
just never moved much and we called her our "zombie cat". Weighing in at
probably TWO pounds, she probably gets a pretty major overdose. Now she
jumps up on things and is much friskier.   I have two horses on it, one
arthritic in hocks, one not.  Don't know if this stuff works or not on
them.  Here goes:   All from Jeffers Vet Supply.
