Megazorb or Kaytee?

[Fluffagrams]

I've used both but generally speaking use Megazorb in most of my cages as it works out to be that much more cost effective than Kaytee which only gets used in maternity or hospital cages.

I find that it can go a bit longer between clean outs than some paper based substrates or shavings and it seems to hold up to burrowing very well.
