Yes, when I used to order grocery delivery via Amazon Fresh, they always came in paper bags. And I was living in a pretty rainy city at the time, but never had any issues with the bags.

I can’t speak for all other animals, but I imagine it’s often for similar reasons as why they do it for cats: removing the hormones means they’re much less likely to display unwanted behaviors such as marking/spraying, territorial aggression (fighting) towards other cats, and roaming. Those behaviors all stem from the desire to mate, and if they don’t have testosterone from the testicles, they don’t experience the desire to mate. Unless you don’t mind the smell of concentrated cat urine everywhere, adult male cats with testicles don’t make very great house pets.

With female cats, they completely remove the ovaries (rather than doing a tubal ligation) for similar reasons. If they did a tubal ligation instead, the cat would still go into heat, meaning lots of yowling and trying to escape, and an increased risk of marking/spraying, just no longer able to get pregnant. In my region, they also usually remove the uterus, but it appears that varies globally.

I hate it because income feels like a number that the studios really care about, but what about number of tickets sold? A movie released this year has a huge head start on box office income when compared to a movie from 20 years ago, since ticket prices have easily doubled. Plus, theatres often have different prices for students, children, seniors, matinees, and even IMAX/3D. So wouldn’t it be more apples to apples over time to compare number of tickets sold, rather than total income?
