Training Cat to Know When It's My Birthday? Elaine E Court St, Middlebury Assistance My birthday was the other day and my cat didn't seem to know or care. Is it possible can train my cat to know when it's my birthday so have someone to celebrate with? I saw the guide on how to train your cat to use the toilet...can this be applied to birthdays? This would make life a lot less lonely. A lot of peolple forgot my birthday this year...and you know who you are, Linda.
