Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner. If you would still like assistance, can you tell me:
Can you confirm your cat is female?
When did she last pass urine?
How long has she been showing all of these signs?
Are her gums nice and pink (not white/pale)? Moist or sticky?
If you press on her belly, does she have any tensing, tenderness, discomfort, or pain?
Can you take a breathing rate for me (just count her breaths for 10 seconds + multiply by 6)?
