2. INTRODUCTION
Nowadays, many people have cats in their homes. They take care of them by giving them food, water.The present design may help cat owners to feed their cats easier.

3. PROBLEM STATEMENT
To design Automatic Cat Feeder (ACF) to supply food and water for a cat at a regular time during the day.

4. NEED ANALYSIS
.Automatic cat feeder. .Food weight controller. .Water level controller. Time regulator.. Does not occupy very large space.. Low cost.. Giving your cat healthy feeding..

5. Store food more than one week
Objectives Tree
Designed (ACF)
Store food more than one week

13. PROBLEM DEFINITION
To design a light , larg and transportable ACF that will feed and water home cats automatically. It's mass doesn't exceed 8 kg without food. In addition, it has 2.25kg as food storage  capacity and 3.54 liters as water storage capacity.To keep ACF be transportable we made two wheels for it to make that easy.

26. Human Factors. #Anthropometric Factors (Dimension):
.ACF dimension is very fit for adult or child human to fill it with food or water.
#Ergonomic Factors:
.It has two wheels to make it's moving very easy.
#Physiological Factors:
.The ACF dose not make any nosie.
.The ACF dose not include any harmful parts
(sharp- poisonous).
.The ACF has electrical protection(preventing shocks).
#Psychological Factors :
1-Good look.
2- Smooth moving (by wheels).
