Dogs with portosystemic shunts or endstage liver disease also have increased uric acid excretion in the urine due to reduced conversion of uric acid to allantoin and ammonia to urea. Urate stones make up about six percent of all stones in the cat. [14] Urate stones can be dissolved using a diet with reduced purines that alkalinizes and dilutes ...
Urine pH is also naturally made more acidic by increasing the meat/fish-based protein percentage in food. Cats with chronic feline lower urinary tract disease caused by struvite uroliths are sometimes treated with a lifelong diet of prescription wet food as these special diets acidify urine which dissolve struvite. However ordinary wet food ...
The symptoms of bacterial infection in the lower urinary tract are very similar to those for non-obstructive FIC (i.e. straining, blood in urine etc.) and a urine test with cultures will be needed to detect if an infection is present. Treatment is usually effective with antibiotics once the result of the urine culture identifies the precise ...
Allantoin is a chemical compound with formula C 4 H 6 N 4 O 3.It is also called 5-ureidohydantoin or glyoxyldiureide. [1] [2] It is a diureide of glyoxylic acid.Allantoin is a major metabolic intermediate in most organisms including animals, plants and bacteria, though not humans.
Various compounds in the urine can precipitate to form crystals. Crystals can be identified based on their appearance and the pH of the urine (many types preferentially form at an acidic or alkaline pH). [123] Crystals that can be found in normal urine include uric acid, monosodium urate, triple phosphate (ammonium magnesium phosphate), calcium ...
Also, long hair cats have less cysteine to go around as the amino acid is also used for protein structures found in hair. Thus, long-haired cats make less felinine than short-haired cats. [12] The urea in cat urine has been found to react with the felinine in the urine.
For example, the liver transforms ammonia (which is poisonous) into urea in fish, amphibians and mammals, and into uric acid in birds and reptiles. Urea is filtered by the kidney into urine or through the gills in fish and tadpoles. Uric acid is paste-like and expelled as a semi-solid waste (the "white" in bird excrements).
By decreasing plasma uric acid levels, help dissolve these crystals, while limiting the formation of new ones. However, the increased uric acid levels in urine can contribute to kidney stones. Thus, use of these drugs is contraindicated in persons already with a high urine concentration of uric acid (hyperuricosuria). In borderline cases ...
