How can I successfully implement DIY cat toilet training for my feline companion?

To successfully implement DIY cat toilet training, start by gradually transitioning your cat from their litter box to a specially designed cat toilet training kit. This kit typically includes a series of trays that fit over the toilet seat, gradually reducing the amount of litter used. It's important to be patient and consistent throughout the training process, rewarding your cat with treats and praise for using the toilet. Monitor your cat's progress closely and be prepared to revert back to the litter box if needed.
