HI, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Daisy!

Daisy could have a urinary tract infection, but most animals do not lose weight with that. I recommend that you take her to your Vet first thing tomorrow. They should get blood work to check her kidney, liver and blood sugar and test her urine for infection or crystals. They may want to take a belly X-ray to check for bladder stones.

Sometimes the urine can be discolored if they have bilirubin in the urine. Cats that are jaundiced are very sick. Check the whites of her eyes, her ears and that thin area of hair above the eyes. If it looks yellow then she should see a vet today.

i wish you the best and a speedy recovery for Daisy

My cat is peeing blood and not eating. Is this an emergency?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Julie! Blood in the urine can indicate a urinary tract infection, crystals in the urine or bladder stones. She may not be eating because she is uncomfortable or has a fever. I recommend that Julie sees a Veterinarian. They may check her urine for infection or crystals. If she is older they may want to run blood work. They also may want to take an X-ray to check for a bladder stone. If it is a urinary tract infection she needs antibiotics. If it is crystals in the urine then we usually change the diet. If bladder stones, ideally surgery is recommended. I hope this helps and I wish Julie a speedy recovery!

My 18-year-old cat won't eat, drinks less, and hasn't pooped. Help!

This is a medical emergency, and Daisy has to see a vet now. It's very serious when a cat won't eat, and if they don't eat going on 72 hours, they will develop a fatty liver which is fatal without treatment. She's probably not pooping because she isn't eating. She has to see a vet immediately, please take her into one right away. Best of luck.

My cat peed brown on the rug. What does discolored urine mean?

Hello, sorry to hear about Mystique. This could be early evidence of a urinary tract infection which may require medications. Female cats are more likely to get urinary tract infections and can show signs such as urinating outside of the litter box, drinking excessive water, urinating more frequently, having a decreased appetite, or even vomiting and having diarrhea. I would have Mystique evaluated by a veterinarian if these abnormal urinations continue or if she develops any of the other symptoms described above. Hope this helps and best of luck.

My old cat is weak, not eating, and has bloody urine. Is she dying?

It is common for cats to hide when they don't feel well. She needs to be taken to a vet to have the lethargy and bloody urine addressed. They will do blood work to check her kidneys function and a urine sample to check for an infection. Weight loss and dehydration can occur quickly in older cats. Your vet can better guide you in her quality of life based on the diagnostics.
