Hello,
I really like having the feed all/play all feature-- it's very nice. But, I'd also love the ability to exclude a den from its benefit. I normally don't chase NCLs or unwanted cubs and just put them up for sale instead, but I generally only do so for a short length of time. The time it takes to get to the point of them leaving on their own is pretty much a perfect timeframe that both allows me to put them up for sale and find takers if someone wants them, but also keeps them rotating through so I can continue to breed/claim. It would be nice if we could choose to exclude a den from the feed all/play all benefits, maybe on the den's page. Right now, I still have to go through and manually feed my pride to make sure I don't have transient lionesses/cubs that are being kept at full needs.
My suggestion would be to add a per-den option that could exempt the den from the feed all/play all benefits. This would help keep things more organized.
