That is terrible,that those other Vets,missed that,and almost cost you,the life,of your Cat.And the sad thing,is that there is very little,that you can do,to get satisfaction,from the Vets,as they stick together,I remember taking Michael,in for dental,only,to be told,3 Moths later,that he needed dental.And the vet,did nothing,when I complained.Sorry,my ex Vet.
