My cat has been breathing quickly (100+ breathes per minute) at rest, and sometimes even panting heavily. A lot of cats in her family died or has been suffering due to kidney diseases.
She displayed a lot of lethargy, lying continuously on the ground and looking very tired, but most importantly she is not drinking water at all. It is pretty hot here in Italy (average 35 degree celsius at home), and she is not drinking water.
We brought her to the vet, which sedated her and did an invasive blood draw. There are a lot of values that are outside the proper range, but the vet suggested to just give her a supplement called "Renal Combi" (https://www.amoreanimaleshop.it/candioli-dog-cat-renal-combi-in-polvere/)
The vet seemed pretty dismissal and he has not a good history of medicating successfully my previous cats (they all died due kidney diseases). I'm really nervous as she is displaying clear signs that something is not good and she is around 13 years old.
I attached here her blood analysis. Apologies that they are in Italian - please ask me if you need the translation of any term.
Thank you so much in advance. I have not been able to sleep for the past week and if you can help my cat it would mean the world.
