We had a cappuccino machine, I
thought my wife kept cleaning the
crispy dried milk off the steamer
spout, she thought I was doing it. A
year later, after coffee every
morning, we found out the cat was
licking it off when we were at work.
Yes, of course be cautious, especially if pregnant. But an indoor cat, even if infected when adopted, won't be contagious after 2 weeks and won't have a way to get reinfected. Outdoor, strays, and unknown cats are obviously not inherently safe.
The book is written in phonetic Scottish, so it's not easy to read, but it absolutely nails the atmosphere, the rawness of the setting.
The book is heavier. It has a very dark storyline that is omitted from the movie, and therefore feels more visceral. The movie is a bit more camp and jovial, but it is absolutely right, I can't fault it, is perfect.
It's a rare case where both the book as the movie are brilliant, but each a whole different experience. I loved the sequel to the book more than the second movie, though, as it is in the same tone, the second movie is good, but not as edgy.
So I would recommend reading it if you have the chance.
