Preparing your home for a Savannah can be similar to toddler-proofing your house from floor to ceiling.
Any breakable objects should either be put away for a year or two, or safely shut into a glass-fronted cabinet. Savannahs are energetic and definitely can be clumsy when racing about the house in a fit of gleeful play.
Secure objects that might be knocked over before bringing your Savannah kitten home. Museum wax/gel is reported to work well for some households.
Remove poisonous plants, definitely. Here is the link to the ASCPA webpage listing plants that have been reported as having serious deleterious effects on animals.
Be aware that a potted plant looks like a lot of digging fun to a Savannah kitten, and the plant itself is “asking” to be dragged all over the house. So, even if the plant is not toxic to your cat you may not successfully keep house plants after introducing a Savannah to your household.
While teething, many Savannah kittens will chew on inappropriate things, including electrical cords. Bitter sprays can be perfect for this, also consider removing and storing any cords that are not necessary at that time. There are also home products available that can encase many cords within the one larger tube. This is a really good idea, especially while your Savannah is young.
Toilet lids should be placed down, as a Savannah kitten will see an open toilet bowl as a “wading pool” and splash around in there. Some Savannahs learn how to turn on water taps, which will either require changing the taps (to a round shape that is more difficult for them) or learning to keep the bathroom door shut.
Savannahs have been known to open doors and drawers. Childproof latches on cupboards containing toxic substances (such as cleaning supplies) is a good idea.
Not ALL Savannahs will be troublesome – it depends on the individual personality and the time they have to themselves. It is best to be aware of situations an intelligent and energetic cat might create. Forewarned is forearmed!
If the kitten is to be left alone for many hours a day, it may be advisable to make a “Savannah-Safe” room to shut the kitten in while you are away. Design it with cat trees, and safe toys, and comfy beds (maybe even leave the radio or TV on) so that it is a pleasant place for your cat to be until you return home.
