Hi , here again my problems with my 5 yo male , he is neutered , he is a healthy cat , a month ago we noticed his many many trips to the litter but nothing came out , we rushed to the vet , she told us it's cystitis no blockage and got antibiotics , them after two weeks he got the same symptoms , urinalysis was done and we got home w antibiotics and prednisolone , today after two weeks again he got the symptoms yesterday but he peed and was fine I called my vet and she told me to watch him closely he peed twice yesterday but he did many trips to the litter box and today he is doing it and he threw up once , I am rushing to our vet but it's 2 hours away from home so it's a long trip and I am anxious , I don't know , I am totally lost , will this last for the rest of his life , is there is anything we can do more , we will do blood tests and urine culture today !
