• Here are some useful websites/stores I like to buy cats’ supplies: 
• Chewy: They have plenty of promotions like ” Buy $100 can get a $30 Gift Card”. And they have great customer service.
• Amazon:  If you have Amazon Prime, it is a great choice for you to get supplies in two days. Sometimes, they have promotions like “Buy $100, get $30 off”
• Petsmart: You can find Petsmart easily in each city.
• Petco: Same as Petsmart, shopping online will have extra discounts.
• Target: Pets’ Bowls are great.  

Supplies:

• Carrier
• Cat water fountain and cat bowl
• Cat scratching post
• Cat tree with scratching Post
• Litter Box
• Feliway
