Yes I have succumbed to the Meeroos craze...and I love it.
I've named him Otis and my pixel heart is already so smitten with him that I can't put him down.
I tried the breedable bunny thing, which didn't last very long, I was never into cats or breedable horses, but this little Meeroo? Be still my heart.
I'm too smitten to give you any good practical advice about his latest SL pet craze, but Chestnut wrote a really great post about the Meeroos so you should go check it out.
