It's amazing how much mice medicine has advanced. At this rate, it won't be long before they become truly invincible.
We should instead worry about super-smart mice, so smart they make humans obsolete. They could ceaselessly try to take over the world - every night!
Mammoths when they saw some oddly clever monkeys.
Mice have a lot of room for improvement. I'll be impressed when we figure out how to double the lifespan of sea turtles.
Why they are sterilizing the cats and not the mosquitoes and the cockroaches is beyond me. Cats can't even fly!
The reason cats are being sterilized is, supposedly, "to avoid indiscriminate reproduction and possible abandonment" of the cats themselves.
The law is called "Animal welfare law" and it's only about pets and their owners. It has nothing to do with endangered or invasive species or even any other type of environmental concern.

The new law introduces quite a few other rules as well: you can't leave your dog alone on the street (e.g. tied to a street lamp while you enter a shop), you can't leave your dog alone on a balcony or in a car, you can't leave your dog alone for 24 hours anywhere, mandatory pet owner course if you have a dog -- although the Spanish article says it's for all pet owners, even birds -- that said, currently the course is postponed because they couldn't prepare it on time; mandatory insurance for your dog, steep fines for breaking these rules, etc.
Working dogs are exempt from these rules. Not only are they being discriminated, but they also don't have a right to minimum wage despite having a job.
