It's Sunday morning, and my cat, age 20, has been barely eating or drinking on her own, for the past four days. Since Wednesday, she has had constipation, lethargy and weight loss. She got 100 units of IV fluid at a vet all day Friday, and then got 50 ml subQ fluids & an enema at the e.r. vet Saturday night. We don't know why she isn't eating/has constipation. She pooped a about 2 inches of stool, not much. Blood tests came back normal for kidneys; calcium is clearly high though not off the charts. The doctor on Friday thinks she might have a tumor in abdominal region, based on exam and a fuzzy and inconclusive x-ray.
My question: I'm syringing food and water, but not much, into her mouth today -- but she fights me & hates it. So do I. It's Sunday a.m. I have an appt. with a top-notch vet who I trust implicitly on Monday a.m. Should I take cat to the e.r. today to get force fed, or just let her be in peace here at home? Right now she's lying next to me, doesn't seem in intense pain or anything (I know it's hard to tell). She came out of her "cabinet" to interact with me a little this a.m. But still very lethargic, no energy at all, very thin. I just want to do what's best for her and keep her suffering to a minimum until we see our top-notch vet tomorrow. So I don't know whether to let her rest here and keep syring feeding, as much as she hates it, or take her to the e.r. for force feeding/fluids. Thank you.
