Easiest option (rather than changing the entire system) is to either lower the cost of food in general, or to increase donations for enclosures (so they can pay for themselves)
We shouldn't need to keep a huge exhibit banks collecting donations, just to be able to pay for our enclosure animals food. My zoos tend to have at least 15-20 exhibits just to offset the food costs of 4-6 enclosures (I don't like running my zoos at a negative profit, even if it is completely viable at the moment).

And on the topic of exhibits,
I hate managing exhibits! Even with long-lived species, I'm always constantly replacing animals (and putting them on contraception). Why can't my keepers just buy a new animal every time one dies and stick it in the enclosure (on contraception) - that really shouldn't be hard to automate. How did they manage to make it take so many clicks to do something so simple! I hate them but I need the donation money to keep my zoo running.
Every time you replace an animal it's hellish - you have to:
- click the enclosure
- click the animal tab
- Click view exhibit animal market
- scroll through a huge list to find the animal you want (why can't it automatically filter from the animal exhibit I clicked from)
- click the animal
- click adopt
- click move
- move it to the enclosure (which I find to be extemely finicky to target)
- click the animal tab
- select the animal
- apply contraceptives (repeat if you bought more than one animal)
This could be done with a single button to purchase a new animal (on the exhibit page) and a check box to put all new exhibit animals on contraception (or automated). /endrant
