The basic problems could involve high blood pressure and thyroid issues, both of which can become serious health problems if ignored. If your cat makes strange noises, it’s a good idea to ask a vet for advice.
Just put some dry green tea in your cat’s litter box to eliminate any bad odors that might spread in your home. Your living area will remain clean and nice-smelling. Your cat will also appreciate the fresh scent while using the litter box.
