Hi Larry,
There are many online chemists available which offers good discounts. I would suggest AskChemist, a UK based online pharmacy store which offers pet products online. Please refer associated address for details

I recommend The Little Pet Store , they were highly recommended on yelp. http://www.yelp.com/biz/the-little-pet-store-brooklyn

I buy for both my dog and my cat supplements from http://www.aussiehealthproducts.com they got some quality supplement for all kinds of pets, in addition the deliver pretty fast.

I highly recommend buying an aquarium at a local pet store. You should look for a store that can offer you good advice, provide solutions to problems and recommend products that are best suited for you. I strongly urge you to visit a few aquarium dealers before choosing a tank.

You can either buy your cat a bed at a local store near you (such as a PetSmart) or online at various retail sites. I will send you a few links; however I highly recommend doing some searching yourself.
