Hi guys, I have a yearling pied bloodred corn that I'm planning to bump up to hopper mouse ( currently feeding on 6-7 gram fuzzies ) . I've read that it's best to slit the f/t hopper prior to feeding to help prevent regurge. Need to know what you guys use to slit the hopper , what part of the hopper mouse do I need to slit , how long and deep should the slit be ? Pics of slit hopper mouse would be great. Appreciate any info you can provide. Thanks.
