The most common cause of death in pet cats is the organ failure specifically chronic renal failure (CRF). Most commonly found diseases in cats are related to its Urinary tract, bladder and Kidney. FLUTD (Feline Lower Urinary Tract Disease) which is a common cat disease leads eventually to CRF and death .
Urinary tract, bladder and kidney problems in domestic cats are dietary related. The most common remedy is to stop the source of such problems which is dry pet food manufactured by large pet food manufacturers.Veterinarians recommend special diets or altogether stop feeding commercial pet foods(which is probably the best choice to increase the life span of cats).
Commercial Dry Pet Foods contain several ingredients that seem to favor formation of calcium oxalate crystals, calcium phosphate, struvite(magnesium ammonium phosphate) stones,
The dry extruded cat foods manufactured by large pet food companies contain significant amount of added phosphate salts such as sodium acid pyrophosphate (SAPP) and tetrasodium pyrophosphate (TSPP) etc. These ingredients are added in liberal quantities in popular cat foods to increase its palatability or acceptance. Cats tend to consume cat foods that contain high levels of phosphates coming from taste enhancers such as SAPP and TSPP. The cats consuming such dry foods or canned foods containing liberally added quantities of phosphates are likely prone to kidney, bladder and urinary tract problems. The long term impact of sodium acid pyrophosphate (SAPP) and tetrasodium pyrophosphate(TSPP) in cat foods has not been studied during the life span of cats. SAPP and TSPP are approved for human food use by the FDA and is regarded as “GRAS”(Generally regarded as safe) but it has not been specifically tested on cats in long term testing or the life span of cats. There are many such loop holes such as what is “GRAS” for humans is ok for pets and this thought is well exploited by large commercial manufacturers of pet foods for commercial success.
Large pet food companies circumvent the labeling of SAPP and TSPP in packaging by calling it chicken flavor, animal liver flavor, natural flavors. So if the label has any such word it means it has SAPP or TSPP
Profit matters but not at the expense of health and safety of our pets
