Cat/pet supply stores in Manhattan?

Hi there, I'm a member from Australia and will be visiting New York in a few months.
Iâ€[emoji]8482[/emoji]d love recommendations for pet supply stores in Manhattan so I can buy my two fur kids some gifts. I will be stocking up on Da Bird refills but am also looking forward to see what other types you have that aren't available at home.
All advice thoroughly appreciated.
Thanks in advance

Just remember you can't bring in feathers (including DaBird) or catnip products. Sometimes DaBird can make it through the mail, but often is confiscated by customs and if bringing in person you would have to declare them.
