I have had my corn snake for approximately 5 years now. He is normally a very good feeder, strikes for his food and eats well (I feed him one jumbo mouse approximately every 12-14 days).
He usually only stops eating for maybe around a month during this time of year (march-april), so when he did the same this year, initially I didn't worry. However, it has been 2 months now and he is still showing no interest at all in any food. I have tried warming the mouse in warm water before offering it to him, making a small cut in it to make it smell more appeasing to him, but still no interest.
However, although looking a bit thinner and weighing less, he is still very active and acting completely his normal self otherwise. I'm just not sure how long I should wait with him not eating before I should start worrying and get him seen by a vet? Any help would be really appreciated. Thank you in advance :)
