so this is the second week in a row i fed the little guy and he regurgitates days after eating.the first time it looked like poop,this time its lighter colored.im taking him to the vet monday or tuesday but wondering wat could be the problem.it looks to me like its been digested so i dunno why he is spitting it out.could he be stopped up or is this a infection or parasite issue?i have not handled him since feeding.any help?
