I have some rat tricks on this website you can teach your rattie. Have fun with it. Will the rattie learn in one day? No. Piture someone from another county trying to teach you something... it may take five or twenty times for them to show and tell you. Just be patient with your small pet. It takes time and patients to train... but worth the effort!!
