This is a very sad poem but i think you did nicely with it..

in this line "is all what there is to eat" it doesnt make sense i think maybe you meant to write "is all [that] there is to eat"

also in the last line you shouldn't put "him/her" that makes this poem seem more like an informative essay or something.. you could do something more general like "its not really [[their]] fault"

I will try in future poems but i do thank you for the input
