If you've had your cat since they were a kitten, you probably have some cute pictures of your pet when they were little.
Be careful: looking at those photos may send you tripping down a memory hole as you remember how cute they used to be, all the good times you've spent together, and how much they've changed over the years.
Instead, take a look at these before and after photos other people have taken of their cats. Some show really dramatic size differences, others capture pets growing up with their owners, but they're all guaranteed to make you think of the first time you met your own cat.
Get ready to go "awwwww," because these are dangerously cute.
