The best way to introduce a collar to your cat is to let them sniff and investigate it first. You might hold it out to them or leave it on the floor in an area they regularly spend time in. Another tip is to rub the collar with your cat’s blanket or bedding, so it’s blended with their scent and therefore feels more familiar. Then, gently place the collar around your cat’s neck when they’re calm. You might try doing this while they’re distracted by food. Give them a treat once their collar is on for positive reinforcement.
