ive made some big cages. some of those captured big biters, but some captured small and medium. when medium biter is captured, it results in medium filled cage, which is emptied to medium empty cage. in time, all my cages become smaller. is that what you wanted?

maybe make 1 kind of cage, and with technology it would be able to catch bigger biters?

That's a good idea, when I started playing the mod yesterday evening I noticed that.

But yeah it doesn't make much sense as it is so I'll do an update around it!

What do you think about the capturing process on general? Plus or minus?

Updated!

youve fixed the problem with cages becoming smaller. it is still clumsy to have 4-8 grinders close by to grind all the different kind of filled cages.
with the normal grinding, all you need is to supply repair packs, but with cages, which do sometimes get destroyed because biter attack it, i need explosives and iron to make new cages. the payoff is too small - the cages result is more or less the same amount of blood. maybe someone else will find a way to make it more effective than me.
actually the cages are way worse then the grinders, because the biters dont die and make that blood gas. collecting blood gas with humidity condensers is even more effective than the grinders - just put 40 of them around the nest => thats much better than that single grinder that gets hit directly.

also, grinder that gets hit doesnt share the biter meat with other grinders, like you said you did
