Most of the cats raised by poop shovelers are pet cats. Whether in terms of physical fitness or other aspects, they are more fragile than our pastoral cats, just like flowers in greenhouses.
When cinders are broken and used as cat litter, there will be a lot of dust inside. If a cat defecates on it, when exposed to these cinders, it is likely to infect the urinary system, which will harm the body.
Although pastoral cats raised in the countryside may be their place to defecate anywhere, their physique will be stronger. So I hope some shovelers don’t have a lucky mentality, thinking that their cats will not be so fragile. They are really sick and there is too little time to regret it.
