Gnarly chompers… this guy recently threw a bit of a fit when i tried switching his pellet brand so he killed 2 heaters. 1 was in a pvc cage and he bit the exposed cord toasting it out. 2nd one was uncaged due to my own negligence and he crushed right through it. Had fun kicking myself as i netted out glass over a few days. 2 new caged heaters added, back to his preferred pellet brand, and hes back to his normal self after a cple weeks. If theres something youve been lazy about over the years… take care of it lol… got lucky on 2 counts of this guy not being electrocuted.
