How about a personalized photo mug with a picture of your husband and a guinea pig printed on it? He can use it every day for his morning coffee or tea and be reminded of his love for guinea pigs. You could also get him a guinea pig stuffed animal or a book about guinea pig care as a thoughtful and practical gift. Another option could be to find a local animal shelter or rescue organization that has guinea pigs up for adoption and donate to their cause in your husband's name.
Or you can get him a star map with the date when he was born.
