I killed my buffie~do not use

I had a Buff not doing well that I brougnt into the hospital (guest bathroom) for recovery. She was not eating and the B.Y.C. folks (ya all are SO nice) told me to get KAYTEE EXACT. Pets Mart was out of KAYTEE so I got LAFERBER'S NUTRI-START. BIG MISTAKE. These two products are made with different flours and react differently to water. Long story short after tube feeding little Buff with the LAFERBER'S, with in 30 min. she was dead. I only gave her 3 - 4 cc total. The LAFEBER'S congeils / becomes very "gummy". So DON'T USE LAFEBER'S only KAYTEE EXACT.
