Gizmo Medical Cost

Our little boy Gizmo has been hospitalized and this is his 2nd opinion and the Vets are baffled. Gizmo was first hospitalized 2 weeks ago for a gastrointestinal infection. He was then released and went back into the vet for a regular check up. He was given more antibiotics and medication this past weekend at which time he developed so bruising. We have never seen Gizmo bruise in this way so we rushed him to our vet.
Our vet ran a bunch of bloodwork and the next morning the internal bleeding continued to spread at which time we rushed our little boy to The Animal Center here in NYC.
He was deemed crititical and has been in the intensive care unit for 2 days already and vets still cant determine what is wrong with our little boy. Between all the visits and the meds, and exams we have surpassed the 7000 mark in hospital bills. We will exhaust any and all possibilities to get our boy better. We have both opened up lines of credit with to help with the cost and we do have insurance for our beloved Gizmo. We are asking for any help in helping keep our little boy alive. We wouldnt normally turn to friends and strangers but the bills are piling up. Sometimes desperate times call for desparate measure. We will continue updating on Gizmo fight for his life
