Cat contraceptive pills can be mixed directly into cat food or canned for feeding. However, contraceptive pills for cats cannot be used for a long time and can only be used occasionally in emergencies to avoid damaging the cat’s body. If you don’t want your cat to go into heat, mate, and get pregnant, the best way is to undergo sterilization surgery, which can completely avoid these problems, prolong the cat’s life, and prevent and avoid reproductive system diseases.
