I too bought a lot of kibble shortly before the update, and since I'm also downsizing considerably, there is no way that my own cats can eat all that food before new year's eve.
What I intend to do, is to calculate how much kibble and milk I need, and donate the rest to
the Saga Charts breeding project space.
All of us use and depend on the Saga charts, which is a project run by volunteers who pay all costs with their own RL money. The breeding space has been up since this summer, and many volunteers have bred hundreds of kitties to place traits in the charts. These kitties would in most cases not have been bred at all if it wasn't for the placement project.
I spent the equivalent of 10 USD on Kibble, and will use at least half of it. The rest, will go to the Saga project, and feed up to ten breeding cats for one month each.
What will I lose? The cost of half a cup of coffee at my local café, one slice of pizza, or one Big Mac. The value I get in return is WAY beyond that cost.
I hope other breeders who have lots of kibble left will do the same, for our common good.
