– Where you should put the litter boxes?

A rule of thumb is that litter boxes should be in spots where cats can find privacy, peace, and convenience.

We recommend putting litter boxes in the hallway or the top of a staircase. These locations are convenient, safe, and light enough for your felines to urinate and defecate comfortably.

However, each cat may have different preferences, so a good trick is researching the places where your cats love to come.

– Where you should avoid putting the litter boxes?

Avoid putting the litter box in the bedroom


Don’t place any litter box in your bedroom as there are dangers of the litter box in the bedroom that your family has to face up with.

Secondly, your family is also at risk of getting Salmonellosis, cat-scratch fever, and some other diseases that result from bacteria in the poop and piss of felines.

Thirdly, cat excrement is full of harmful parasites that are prone to infect people, such as Toxoplasma gondii, roundworms, hookworms, and ringworms.

Last but not least, your bedroom is often a dark place that felines cannot see themselves when they eliminate, which is unfavorable for their nature.

Avoid putting litter box near the water heater


As we mentioned above, there is ammonia in the piss and poop and cats. In addition to harming the human respiratory system, this gas will reduce the longevity of your water heater with corrosion over time.

Besides, a water heater is likely to be a dangerous appliance for your mischievous kitties.

A little kitty meets difficulty in climbing up and down the stairs will not like a litter box in the basement or a high story.

Also, places where people often go by like foyers or areas where there are noisy devices such as washing machines and industrial fans are neither ideal positions for litter boxes.

It is common sense that putting a litter box in the closet and a litter box in the laundry room will cause your clothing to smell bad, so we do not need to talk about this here.
