Question:

How worried should I be about my cats USG? (1.026 to 1.015 in a month)

I’m really worried about my cat, Luna, and could use some advice. Last month, during her annual check-up, her vet did some tests and said her urine specific gravity was at 1.026, which I thought was normal. Just yesterday, we went back for a follow-up because she's been drinking water like crazy and peeing all over the place. Her USG has dropped to 1.015. Honestly, I'm getting a bit anxious and don't know if this is a sign of something serious. I love her so much, and the thought of anything being wrong is really stressing me out. Has anyone else experienced something like this with their fur babies? What did it end up being? I appreciate any insights or advice you might have!

Answer:

Hello there! It’s great that you’re monitoring your cat’s urine specific gravity (USG), as it can provide valuable insights into their health. A drop from 1.026 to 1.015 over a month can suggest a few things.



USG measures how well your cat’s kidneys can concentrate urine, which is crucial for hydration and waste elimination. A lowered USG might indicate that your cat is drinking more water, possibly due to increased thirst, or it might be a sign of early kidney changes or other conditions like diabetes or hyperthyroidism.



At home, ensure your cat has constant access to fresh water and monitor their drinking habits. Take note if they seem thirstier than usual or are urinating more often. Encouraging hydration by feeding wet food can also support kidney function.



Keep an eye out for signs such as lethargy, weight loss, changes in appetite, vomiting, or a noticeable increase in urination or thirst, as these can suggest more serious issues like early kidney disease or metabolic disorders.



To delve deeper into your cat’s health and address any concerns you may have, I recommend booking a video consult with a vet through Dial A Vet. They can provide a more detailed analysis and guide you on the next best steps for your feline friend.

just chilling on the couch with Max and munching on some dried mango. Is it cool if he has a nibble too, or is that not a thing? Not sure if this is dumb, but he's giving me those puppy eyes!

just got home from the dog park and found my partner sharing their steak with our golden, Max. he swears it's fine, but now Max is eyeing my dinner too. so, can dogs actually have steak, or should i start hiding the t-bones?

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
