Please help pay for Surgery to repair Gizmo’s jaw

Hi, my name is Rachel and I am mummy to 2 1/2 year old Sphynx, Gizmo. I am currently very limited as to what I can say about this case except that this was not an accident. Gizmo has been subjected to such a trauma that he has 6 fractures in his skull, including a broken jaw. He did not deserve this. Surgery is required to put a metal plate and pins in to allow him to eat, clean and maintain a hopefully normal life moving forward. Gizmo is insured but they will only pay up to £4000. I have currently used £2300 of this already so far on scans, xrays, medication and pain relief. Surgery is estimated at £5500, leaving a shortfall of £3800. Giz is the most amazing, loving and clever boy I’ve ever had. Even through all this he has still been giving me snuggles, love and purring his heart out, even with the vets and nurses! Im honestly in awe of how strong this little guy is. So anything at all you can spare would be so greatly appreciated. I know how hard life is for everyone right now, but please help me and Gizmo in anyway you can, every donation counts. Thank you for reading
