I feel sick...

Is there any information about what age CO2 starts working properly? I assumed weanlings no longer under the mothers belly would be susceptible to CO2, or more like small rats?

Im not really sure. I was just repeating that so you knew why it might not be working on them if you tried it. PM satomi, she knows alot more than me about this stuff and what size is safe to gas them at.
