Keeping wild and exotic animals like mongooses at home and in the garden is very difficult and burdensome and
therefore often not recommended!
Most of the mongooses-species are very social animals, feeling comfortable only in a larger group. They need social structures and contact within the family - this is easily demonstrated in the need for communication during mutual foraging and scratching the grounds.
For social animals like mongooses, there is nothing worse than being alone - loneliness causes mental stress and severe suffering!
Mongooses need lots of space to roam. They are very intelligent, extremely active and used to scratch their food on vast expanses of sand, gravel and grassland.
Those animals have high demands on their environment - providing shelter in a small and bleak enclosure or even an apartment would simply mean pain and agony for the mongooses!
Out of love for animals, keeping of mongooses should be considered very carefully!
Purchasing and keeping animals out of a mood (or because it's hip) should never ever be approached! Please refrain from keeping animals if it's not true dedication to animals which induces the keeping!
Keeping of mongooses requires detailed specialist knowledge. The needs of the animals should be clearly identified well in advance. The expense of appropriate animal care is not to be underestimated - keeping of mongooses implies a high degree of knowledge, learning, understanding, commitment and attention!
