Our family pet JET has diabetes and has now formed cataracts she needs surgery to restore her sight pet insurance was not worth squat. We were originally told around $2500 for the operation but it has come in at $8000 vetpet loans would not help us either we have applied for a loan but not hopeful. We have already sorted her diabetes and now we want to go the next step and restore her sight.
