Sally, I use Alice.com for all the things you listed....well, except for the dog food.....and I love it! They usually deliver within 2-3 days and it's so much easier than trying to lug big packages of toilet paper and paper towels home.

For cat food and pet supplies I use Petco.com. I get free shipping and 5% cash back that I can use on my next order.

Plus, I go to these websites through ebates.com so I get an additional 5-10% cash back on the purchases. Every little bit helps!
