I never understood the waiting reason because there is always something going on in life. You have to plan around school, work, family and friends, hobbies, sleep. That’s life, you just make it work (or don’t).
Are there no real cats in that world? Can I even trust my two little kitties sleeping peacefully on my bed? Maybe they're freeloading humans... now that would be terrifying.
For at least a full year too. This is the most unrealistic part of their relationship. No man or woman ever lived that had the self-control not to do anything while sleeping in the same bed as a love interest for as long as they have.
