So, since December my cat lost 4 pounds. My husband and I noticed the weight loss which was gradual but his behavior and appetite did not change. We decided to take him to his primary vet on April 11th. They did bloodwork and based on high levels of phosphorus, WBC, and other elevated levels said he probably has CKD. They recommended an ultrasound to look at his kidneys. We also started him on a CKD diet of Hill’s wet and dry food and Epakitin. We had the ultrasound done and the tech said his kidneys are unexpectedly enlarged and not shriveled which is more common in CKD. They recommended we see an internal medicine specialist for follow up bloodwork and thoughts on what to else he could be fighting in addition to possible CKD. We had his blood work done again on May 1st and even the specialist is puzzled. We still don’t have a definitive diagnosis and said he could possibly have lymphoma. They are giving us a steroid for him or said we could do an aspirate test to check for lymphoma which may still not give us a definitive diagnosis. Some of his bloodwork levels did improve but his WBC are still high and his RBC are still low which is concerning with the anemia. Here are the first and second blood tests. Our cat is only 5 years old, still has a healthy appetite, and is running around, grooming, and being a typical cat. Has anyone had something similar with their cat and would you recommend starting him on a steroid? The first 2 pictures are of his first appointment and the last picture is from his most recent appointment. We just want to help our little guy, we love him so much.
