Succulents come in MANY shapes and sizes, but the care remains the same. Most succulents are pet friendly, but there are some specific ones that can be toxic. Anything that has sap when severed should be considered unsafe for pets.
Lighting: They can tolerate around 5-6 hours of direct sunlight touching the foliage. Lower light will result in stretching, likely won't stay compact, and may need frequent pruning. To maintain these plants, a minimum of 400 FC is required, but for good growth, you want around 800 FC.
Watering: These plants like to dry out all of the way between waterings. Succulents store water in their foliage and can be easily overwatered. Wait until the soil is completely dry and the foliage is no longer plump.
This quick cheat sheet is meant to give you tips and tricks for how to best care for your plant. All of the information above is based on my personal experience and advice with houseplants and the lighting requirements are a reference from Daryl Chang of House Plant Journal.
*FC is lighting measured in Foot Candles and requires a light meter to get an accurate reading.
