my persian male cat who is 5 years old had a urinary blockage and i had to take him to a emergency vet hospital last night who put in a cathater to remove particles. He was clear after the 2nd flush and they told me that they recommend a fluid treatment but I had already spent way too much and basically took him home to take care of him. They removed the catheter the next morning and gave me some canon royal to feed him and told me to put water out all over the house. So when we got home he peed alittle and then ate a tiny bit of the wet food but has barely drank any water. He's very upset and hasn't been trying to get any attention. He also looks a bit tired. So what can I do to help him drink and eat because I can't afford to spend any more on vet visits. Please give me some advice, I heard that maybe giving him some cranberry juice diluted with water might help is that true?
