What does the Catholic Church say about having cremation urns at home?

I've had my late grandmother's ashes kept in an urn beside my bed for many years. We were very close and this way I feel like she's still close to me. The problem is, I recently joined the Catholic faith, and I'm not sure if I can still keep my grandma's ashes in my home. Can someone please tell me what the Catholic Church says about keeping cremation urns at home? This is a real moral dilemma for me. Please help!
