guinea pig becomes reasonably close 3rd to dogs and cats, with Princess Diana’s fandom 1981 + better litter

[GeographyDude]

An 11-year-old Diana posing with her guinea pig Peanuts. I remember this picture (or similar) from an American magazine at the time of the Royal Wedding the Summer of 1981.

Combined with advances in the litter (certainly, products can be drawn from cat litter, I mean for crying out loud! ! !),

please paint a picture of the guinea pig being a significantly more popular pet. Thanks.
