Ideally now would be a good time to figure out some kind of balancing mechanism which controls the flow based on active population. (yeah I know, I've been banging on about this for years)
If it was me I'd go one step further and run a script to locate collections of > 30 stacks of the same quality cats and destroy the excess.
Both good ideas and imo proper solutions to the problem. 90% reduction is too unlikely to work.
