Atticus is close to 600 grams now, and I've been feeding him 2 adult mice per week due to the shortage of jumbo mice. Two questions:

1. Is he big enough to graduate to small rats? I haven't been able to find the weanling size at the local stores

2. Are there any other viable prey items of decent size? I have been struggling with the idea of feeding rats simply because they are such great pets. I realize this is somewhat ironic given how much bacon I eat, but I'm going to ask anyways

Thanks
