I guess any animal that's not a cat can get fucked.
I remember being into Tradewinds, so I do like these buy low sell high merchant games. I love the quality-of-life features you've included, like telling me what the base price of a tea is. In a lot of games like Tradewinds, you just have to figure out for yourself what the "normal" price of an item is.
I was a little confused at first because the cat tooltips just use the name of each tea and your stock shows the tea based on pictures, so I thought I had to go back to the menu to remind myself what the name of each tea was, but then I realized you can tell based on the listing order. Still it might've been nice to be able to hover over a tea icon and see its name.
I quickly discovered that the game gives you free rerolls. You can keep switching between the menu and the map until you find a cat that has the right prices for you. Maybe you should've kept the prices fixed so that they only reroll when you do a run.
I think it's too bad that the cats only have about 5000 pounds each time. This removes an element of strategy from the game, since once you accumulate a nice stock of cash and tea, you can easily clean out every cat you visit so you don't really get much of a reward for smart trading.
Like future cop said, I realized before I bought any photos that it makes the most sense to wait until the end to buy any. It would've been nice to have the total value calculated for you so that you know how much to save up.
