LPT: I see a lot of cute gifs of people surprising other people with cute dogs and cats. DON'T do this.

These are living things that require a big amount of responsibility and commitment. When the person who gets this doesn't really want it, it will end up in a animal shelter. Also if the person does want a pet it's much better to let them pick one that they feel will match their personality it will make their connection to their pets better that way. Also when you give pets to little kids, don't expect them to take care of them. They won't.
