Assuming you are asking where the best place to put a cat water fountain is, here are some tips:
1. Place the fountain near your cat's food bowl - this will encourage your cat to drink more since they will already be in the habit of going to this area to eat.
2. Put the fountain in a room that your cat spends a lot of time in - this could be their bedroom or a room where they like to lounge and relax. By putting it in a space that your cat frequents, they will be more likely to notice and use it.
3. Make sure the fountain is easily accessible - cats can be fussy creatures and if they have to work too hard to get to their water, they may just give up and go elsewhere. So, placing it in an open area with no obstacles nearby is ideal.
4. Keep the fountain clean - as with anything else in your home, if the water fountain is dirty, your cat is unlikely to want to use it. Make sure you regularly clean and refill the unit according to the manufacturer's instructions.
