Big cheese is my first choice, but as others have said, they always seem to be out of at least one of the sizes I need (most often rats) when I order.

Perfect Prey is usually my backup. They are a little pricier per rodent and with shipping, but the quality is good IMO.

I've also used south Florida rodents.. They used to sell f/t asf also. But they are a good bit more expensive per rodent and shipping.

I bought from feeder source once at a local show. Quality was good, but their online prices are expensive IMO.
