Hello, I'm new to the site and looking for peace of mind. I have a 14 yr male tabby, Gibby, that has led a pampered life. Yesterday, took him to vet for surgery for a blocked bladder. Kidney results slightly out of norm but vet thinks ok. Gib is on fluids/catheter. WBC and RBC very low but did test negative for Fel Leuk. Being referred to specialist in search of tumor. Could bladder issues confound hematology results? No rapid weight loss, no vomiting, no diarrhea, no distensions, no masses. 24 hours ago, he was the same ol' Gib. Something not right, the vet, the tests, me or Gib. Any thoughts? Thank you in advance.
