Training your cat to poop in one place can take some time and patience, but it is definitely worth the effort! Start by providing a litter box that's large enough for them to comfortably turn around in. Make sure you clean up any accidents quickly and thoroughly so they don't associate the same spot with their bathroom habits again. In addition, try putting something like newspaper or aluminum foil over other areas of your home where cats have gone before. This will make those spots less inviting and help them better understand where they should go instead. You may also want to reward your cat when they use the litter box correctly with treats or praise - this will encourage positive behavior while reinforcing that going elsewhere isn't okay. Finally, be patient as it may take awhile before your cat finally gets used to using their designated area!
