I took my 18 year old cat for some grooming last week, she had some bad matts on her and I just couldn't get them out. Shes a wild woman in the vets office so they had to sedate her long enough to do the job. She came home looking groggy and not feeling well. She continued for two days and I called the office to see why she would be so long recovering. They told me sometimes older cats have a harder time recovering. Well that night she got very sick, vomiting and dry heaves. Poor girl, had to rush her to the vets first thing that morning. They found she had a severe urinary tract infection. She never showed any of the telltale symtoms, so that confused me. She was given antibiotic shot and one for nausea and a couple other things...so far in less than two weeks it has cost me $600...my question is has anyone else experienced this with their pet? She still is very very tired and is having a hard time recovering.
