its normal for them to not wanna eat. maybe he's just stressed cuz u just got him. anyway this site will help u not wanna slit ur wrists. they helped me wen i just got my abby. god she wudn't eat n now 2.5 months later she still wont eat much but like everyone says they are just sooooo small. i think they shud eat 1/10 of their weight a day. soo figure if he's 2lbs, then he should eat like an ounce or two of food a day (i'm really bad w math so forgive me if im wayyyyyyy off)
just make sure to keep him hydrated n give him nutrical if he's not eating to keep his sugar levels up. give him lots of hugs n kisses. it will get better... try the boiled chicken tho
