Unless you can convince your local standards authority that the cat water fountain you bought is actually a weird looking portable speaker, I don't think this law applies her.

Unfortunate, really, because USB port really shouldn't use non-standard voltages. I'm sure there's some consumer protection law you could use in court to make the manufacturer pay for damage if they damaged your devices (there are a bunch of "a product should work like you would expect" types of laws sprinkled across consumer protection laws) but I don't think this violates CE standards.
