I read that real fur trees are dangerous for cats, since the needles can puncture their intestines if swallowed. Pine trees have softer needles but more toxic
if chewed and swallowed. After reading that I changed my mind about real tree and settled for a small 3 feet green tree with fiberoptic ends. Cats don't chew on it,
and do not touch few decorations , so I feel safe. It does not take much time to plug it in and decorate.
