I don't think any of them sell the lab blocks. ... only been on lab block for about.. 6 months. fr0glet

Why don't they sell them? I used to special-order them from the local feed elevator, but that was a pain. Cindy

My guess would be not enough profit margin. shrug

I don't think any of them sell the lab blocks. Ours comes in for store use only. And the rats and mice have only been on lab block for about.. 6 months.

Our local Petco used to sell lab blocks (meaning we no longer have a local Petco, they closed the store, not that they stopped). Petsmart does sell lab blocks.
