hi, how can i change my jcp diet from mice to rats? i have 2 jcp both around a year old,the female is regulary feeding on f/t small rats but my male won't accept rats,he only wants mice, i've tried chain feeding him with rats after offering a mice fuzzy,problem is he will simply let go of the rats when he realize its not a mice,help pls... will it help if i will not feed him for around a week or two? thanks in advance
