I cleaned my G. porteri’s enclosure and gave her fresh substrate today. It wasn’t really necessary, but wasn’t too much of a hassle. She’s had the same dirt for two years which isn’t a big deal– spot cleaning is usually more than enough to keep an enclosure tidy. If she was a P. murinus I would have never bothered, but she’s slow and docile and I had a fresh bag of coir and didn’t care for the top soil I used originally. It’s also more lively with some sphagnum moss and fake flowers added in.
