Excellent with people and loves to be the center of attention. He is always at the door of his DCN ready to climb out on me. Pettings are his favorite and will even gently grab my finger to try pulling my hand in the cage with him to continue being pampered! He has a very strong respiratory system and has not had even one respiratory flare up nor have I seen him sneeze! The only issue with Jake is he has very mild hormonal aggression - he can still live with his friends, but no new rats can be introduced. Due to this, he will only be bred if he lives exceedingly long continuing not to have any health issues.
