Good article, but I think she should have stressed dry feeding more so.
I think two HUGE culprits are dry feeding (first) and household chemicals. A cat doesn't have to ingest/lick a household cleaners, candles, air fresheners, etc. for it to be deadly... the "fumes" often do serious damage.
PS Too often a cat's death will be "explained" as kidney failure... but the vet never tells the pet owner WHY the cat had kidney failure. Example... a person's cat got severely ill after the person installed a plug in air freshener. The pet owner suspected the air freshener and shared that info with the vet. The vet didn't tell the person ONE TIME to remove the air freshener. He just treated (somewhat) the cat for kidney failure. The cat died. The person still uses air fresheners, floor cleaners, etc... and has other cats.
There was also a situation where a cat was having severe kidney issues and the vet recommended giving the cat fluids. Didn't say a peep about stoping the kibble. Cat died.
