where on the site can you get food and toys at?

the main shops are the place to find all sorts of items. they're organized by what they sell so you should be able to find anything you're looking for. you can also find items in user shops using the shop search. subetalodge is a great fansite for finding all sorts of items and learning where you can buy them.

Welcome to the site! I suggest you looking at this board for all the basics and such. :)

also is there ways to see what colors pets come in?
