Level 23 comments, including the cat

The excellent vianovaus's walkthrough for level 23 on this forum advises expanding your storage first thing, and is absolutely correct. I don't think the level is doable otherwise.

I don't know if the game automatically offers it, but even if not the Shop will sell you a first expansion of your vehicle (technically from "car" to "truck"), so that it can carry 3 boxes at a time. Spending 300 gold pieces on that upgrade as soon as you have it also helped me on this level.

Whenever there was room on the truck, I sold any raw wool available, rather than waiting for it to be spun, thus clearing space to get yet more wool into storage. Note: On this level that's what counts, NOT the number of spools.

The walkthrough also advises that after you get going, "you can just cage the bears that fall without having to sell them". Frankly, at any level, I have great difficulty fully caging bears without also getting them into storage--unless storage is already full. Sometimes I'd like just one, but when they're all in a crowd, apparently it's click one, click all, and as many as will fit get transferred. And then I may have to sit and watch as product--say, wool--evaporates while waiting for the truck to get back from town.

After I had a few sheep, maybe 5, I hired a cat for 2500 gp (the price of 2.5 sheep) to find and bat the wool sacks in for me. By then I had quite enough to do attending to everything else--including making room in storage for more sacks to be batted in--and of course it got worse as I added even more sheep. I don't think I could have come in under the gold time without the cat.
