What You’ll Need
Basically, all the materials you’ll need to teach your rats this trick are yourself, your rats and some kind of treat to reward them with. We give our rats Yoggies Cheese-Flavored yogurt treats for rats, and they love them. They love them perhaps a bit too much, and often beg for them by giving us kisses and doing all the other tricks we’ve taught them, just to get the Yoggies. You can also use baby food, bananas (just a little bit of mashed up banana), or fresh leafy veggies. Oh, and the one ours used to go crazy over: applesauce.
Next, you just repeat that process until they’ve understood exactly what you want, and then, you just start adding the command. For ours, its “kisses” plus the rat’s name. Just say your command word, then do the pucker like you usually do, and reward them when they get it. Eventually, you can just say the command, and they’ll go to kiss you on their own, without you doing the pucker.
Just remember, always use positive reinforcement with rats, not negative. Rats are incredibly responsive to positive reinforcement, and are very fast to pick up a new trick. Usually, once one of the rats has done a new trick, the rest learn it much faster. Always remember, first teach the trick, then teach the corresponding command.
