Dry food for my cats inside: local mom and pop store that carries EVO.

Dry food for the strays outside: local supermarket, pet chain store, or walmart. Depends on where I am when I run out.

Litter: have been buying MiMi pearls crystal litter from Walmart. Can't find it anywhere else.

Toys: depends where I am when I find them and think "oh! that's cool!"
