Many wood cat shelves and trees include stability features such as thickened boards, wide or heavy bases, anti-toppling devices, and anti-slip footpads to reduce tipping risk. Some models advertise reinforced or sturdier bases. When shopping, check the product listing for explicit anti-tip hardware or wall-mount options and review weight limits to match your cat(s).
Many include removable bedding: window hammocks often have detachable canvas covers that can be machine washed, several trees have removable mats or plush cushions (some recommend hand washing), and some top-perch cushions are thickened and removable. Always check the item’s care label for recommended washing instructions.
