I have 5 African land snails for snail. Varying in age. Youngest is only a few months, a couple are around 9 and an older one who is about 15 months.
Easy to house temporarily in a large Tupperware but plenty of enclosures can be found online. They eat all your salad bits (ie lettuce cucumbers tomato spinach) need a source of calcium such a cuttlefish. Plenty of other info online. Need cocopeat soil
deep enough to bury and a source of warmth in colder months. Enjoy little baths in warm water.
Snails are hermaphrodites so have both gentiles.
