Oh Wise One
If you are going to change something, change the most useless Wonder of them all, Thrones of High Men. Make it like other Wonders that provide one per week of an item, with an increase of one every 5 levels, so at level 30 it would give you 7 pet food, once per week. Then after collecting, you could at least have one for each day of the next week.
The most useless wonder was suggested and the most useless of its features too. Straight swap to pet food with 1 per week on lvl 1 isn't too bad. Thrones is very handy but not early on, in conjunction with monastery/sanc and watchtower it allows you to not need a single culture building(or minimal depending on build)
