What are 4 things that pod and homily fear in the borrowers?

Pod and Homily fear the following things in the Borrowers:

1. Arrietta. Arrietta is very curious and brave, which are both traits that the Borrowers try to avoid in humans. She always wants to know more about the Borrowers and has several mishaps with the family throughout the story.

2. The cat. The cat is a natural predator of the Borrowers, and they are very afraid of it. The Borrowers know that the cat would eat them if it ever caught them.

3. The housekeeper. The housekeeper is very thorough in her cleaning and could destroy or throw out Borrower things. Arrietta and her younger sister run into her several times while borrowing objects.

4. The gardener. The gardener turns up the garden without being aware that the Borrowers live in it.
