Plot hole: Dora is sleeping after being taken to the hospital, she wakes up in Paul's bed. Assuming, she recognizes the place as the one where the fundraiser/party is held, how can she know that it was Paul's bed and that he lived there? Furthermore, she also seems to know that she was in the hospital, and that Paul was the one who took her. Seeing the exchange of dialouge between Paul and the doctor, and Paul and her, there was no way she could have known that information prior to her waking up.

Factual error: When Dora and Paul walk into find the newborn baby kitten on the floor, it shows what a kitten would actually look like if it was newborn. However, after they save it and are with all the kittens later on, the kittens are walking around and they have their eyes open. Kittens don't open their eyes or walk for at least 2 weeks after being born. In the movie, they had just been born.
