Help Give Sally a brighter future

This is Sally she is 4 months old we picked her up from a pet shop when she was 8 weeks old we were so excited we found our perfect baby to only notice within the first day something wasn't right. Sally has a rare Birth defect Cricopharyngeal dysphagia( her mussel in her throat tighten when she eats so eating is a struggle and its not a nice sound when she eats) she needs urgent life saving surgery. The pet shop are not interested in helping unless we want to swap her we have not been offed a refund and believe they should not pay any vet bills. This is a matter I will be taken further. She is a bright lovely sweetheart and she doesn't take long to win your heart over she has been booked in for surgery on Wednesday the 6th of June till then she is on 1 teaspoon of special meat 2 hourly.
