so my bp whom i bought in october, has been on a diet of rat pups and then medium size rats since i bought him and within the last couple of months i have found my self buying rats and then he just strays away from them or curls up as if he is afraid. i then try to maintain the rat for about a week with no success. Repeatedly introducing them and he just does not want it no matter how long he has not eaten. I went to the pet store and bought 3 mice to try to balance the amount of weight of the rats and he took to them as soon as i placed them in his tank. What seems to be the problem? Is he afraid of the rats, or does he just not like them anymore, should i keep him on the 3 mice every 10 days diet or what? Med rats 4.99, 3 mice $6.00 Thanks for the help
