Well its been a little over 2 weeks now that I posted this and I just want to comment on what I have noticed. First... TSC flake pine shavings... I haven't seen any sneezing or deaths from my colonys, so I am super happy with it and I am going to keep using it. 2nd....As for the Doggy bag dog food my rats seem to love it, but the only thing I see negative about it is it makes my rats coat look rough and their poop is more like diarrhea, so if you don't mind that its not bad...again my rats love it. I am definitely going to be using it as a mix with Mazuri for a different taste for them. Hope this helps people like myself looking to save money.
