I'm worried about my cat. A month ago i woke up on a Saturday morning and she was just not right. I knew something was seriously wrong so i called my vet who said they were booked up and couldn't see us so they gave me a couple of other vets to try. I called one of the others and they were booked but they said to bring her in and they would do tests etc and then see me in the afteroon. As it turns out, they were able to see us when i got there. The vet noticed some pain in her lower stomach area and recommended a bunch of tests. They did X-rays, urine, blood etc. When they were extracting the urine with a needle they withdrew a bunch of pus. To make a long story short, they determined she had some kind of abcess/infection and gave her a major dose of antibiotics and iv fluids. That day she was horribly depressed and i was sure that i was going to have to put her down. She was literally looking at me and saying "help me". Sunday was the same and i was preparing myself for the inevitable. Sunday evening she perked up and by Monday she was fine! The vet said to bring her back in 2 weeks for another antibiotic shot and taught me how to administer sub-cutaneous fluids (she has some kidney disease). All was well, she was eating like never before (new prescription cat food) and she was super perky after her water treatments. I noticed the last few days she wasn't finishing her food and when the vet called this morning to see how she was doing, i mentioned that, and that she had vomitted a few times. They said they would have a vet look at her file and get back to me. Since then my baby has been going to the litter box incessantly but not able to get anything out. At first i thought she was constipated (which i'm sure she is) but she's not peeing either. I gave her some sub-q fluids and called the vet back and they said they would have the vet call me when he had a chance to look at her file. It's just breaking my heart to see her trying so hard in her box. She gets in, strains, nothing happens, she hops out and then turns around and hops back in. She has been doing this for about 2 hours . It's killing me.
