Alright I bought a couple fake plants from hobby lobby last night, got them home and the stems are way too long for my tub. They are metal wire covered in plastic, so how do I cut them? Also should I sanitize them before putting them into his tub? And last but not least, he hasnt eaten in 2 weeks, he refused the last 2 mice I went to give him. Should I wait till hes eating well to put the plants in?
