Here are two adorable fleece like polyester beds can be used for Guinea pigs, mice, gerbil, or rat. Nice soft material keep your pet warm especially on a cold night. Said to spot clean but I have machine wash them in warm water and they come out fine. Comes in blue and pink. Your Guinea pig would love to cuddle in this bed when they are first born up to a year. After, that Guinea pig will grow much that maybe too big to fit the bed.
