Help Benny's Emergency Blood Transfusion

Our sweet 6 yr old Benny needs an emergency blood transfusion. Benny had not been acting like himself, so we made an emergency trip to the vet. Upon further testing it was discovered that Benny’s red blood count is at 9%, way below the normal requiring a blood transfusion. We have found an animal hospital that has cat blood, but the transfusion, hospitalization and testing will cost approximately $6800. Benny will currently not eat on his own due to being so lethargic, so we are now feeding him and giving him constant 24hr care while we try to gather enough funds. Myself, my husband, and our 3 daughters are devastated and want to give Benny a fighting chance. He is such a kind and loving cat, and the thought of him not surviving has left us extremely heartbroken. Anything donation would be so much appreciated. Prior to this, Benny was an active, energetic, and healthy cat. Thank you!
