HEY HOMER!! I had that exact same cage back when I got my first pair of rats (2001)! I just LOVED it, and so did my ratties, but WOW did that baby ever soak up the urine! I had to get rid of it in a year or so because it was so nasty! I miss that cage it was great!

p.s. your children are ADORABLE!!! *belly kiss & poke*
