I have a 16 year old farm cat that had injuried his hind leg. I took him to the vet and it was determined that he had a large hematoma and that he just needed rest and time to get well plus a few days of metacam (anti-inflamatory). This occured about 3 weeks ago. Things were going well and then he started acting lethargic and not eating very well. I took him back Tuesday and they ran blood work on him. His BUN and creatitnine levels were elevated but his phosphorus was in the normal range. He also was diagnosed with a bladder infection. Vet was concerned about CRF but with the normal phosphorus level is hoping that the high BUN and Cre. were due to the bladder infection. They kept him overnight and gave him Sub-Q fluids. His kidney values were rechecked the next afternoon and they were a bit better but still high. He was started on Baytril (anti-biotic) and sent home. He still will not eat. I picked up more fluids Thursday and he's had 2 days of Sub-Q's administered by me. Thursday night he finally ate some raw pork tenderloin. (I had previously tried wet food, tuna, and raw rabbit; all of which he normally loves) The pork was the last thing he willingly ate. I've tried Fancy Feast flavors, Sheba flavors, tuna, rabbit, pork, clam juice, and chicken baby food. He refuses it all. I force fed him the chicken baby food last night and this morning but I'm getting really worried and frustrated. Does anyone have any suggestions? Since its the Memorial Day weekend, my vet is closed until Tuesday.
