We have a 3 year old WT. She has recently started urinating in her bed during the night, she then will lay back in her bed. She also will squirt several times when she is out for her walk. Is this common with WT'S? I am more concerned about the bed wetting.

Has she been spayed? This could be one of the known side-effects. Otherwise she could have a urinary infection. Get her checked by your vet.
Good luck.
