Chronic Renal Failure (kidney disease)
Persistent thirst and frequent urination are the most evident early indicators of Chronic Renal Failure.
If you use clumping litter, you may observe larger-than-usual urine clumps in the litter box.
You may see your cat elevating his backside when urinating, causing him to overrun the sides of the litter box.
The cat will do this to prevent urine from pooling around his feet since he is urinating in excess.
The cat may feel nausea, loss of appetite, vomiting, weight loss, poor fur coat, and emaciation as the condition worsens.
It might be difficult to detect if a cat is malnourished simply by looking at it, especially if it has long hair and is fluffy.
However, if you feel the cat's body behind the fur, you can tell whether it is emaciated since all you feel is skin and bones!
Because just 30% of kidney capacity is required for proper operation, no symptoms will appear until about 70% of renal function is lost.
It is critical to initiate therapy as soon as the first symptoms occur because the cat has depleted its reserves and would die shortly if not treated.
