A Savannah is not a cat you maintain; it is a cat you schedule around. It needs an hour of structured activity a day, a ceiling-height route through the room, and a screening plan, because three inherited problems are testable. Skip the first two and the cat dismantles the house; skip the third and a collapse may be the first sign.

Early generations (F1-F3) are bigger, wilder and more expensive to keep than later ones, and the care calendar differs mainly in how much space and screening they need.

Space: the numbers that matter

Count vertical metres, not floor area. A Savannah needs a continuous climbing route of at least 2.4 m — shelves, a tall tree, the top of a wardrobe joined by a bridge — plus one high perch per cat. A catio of 3 x 2 m with a solid roof beats an open garden, because these cats clear a 2 m fence without effort and cannot be trusted off-lead.

Weight and condition across the generations

Adults run 3.6-9 kg depending on generation, with F1 and F2 males at the top and later generations near 5-7 kg. The silhouette is tall and narrow, so a healthy cat looks lean. Weigh monthly; a 5% loss in a month is a veterinary question, often gut disease rather than fussiness.

Feed two or three measured meals, high protein, no free-feeding. An active 6 kg adult needs roughly 280-330 kcal. Because digestive sensitivity is common, keep one staple food and rotate only treats. Transitions take 7-10 days at 10% increments — a Savannah switched in two days will produce loose stool for a week.

Screening: HCM, PRA and PK deficiency

Hypertrophic cardiomyopathy is the breed's worst documented threat, and early-generation cats have died suddenly in their first years. Baseline echocardiogram at 12 months, then every 12 months for F1-F3 and every 12-24 months later. Any murmur, or a cat tiring on stairs it used to sprint, moves the scan up.

Progressive retinal atrophy can be tested for in some lines; one DNA swab gives the genotype, and an affected cat needs an annual dilated exam. Pyruvate kinase deficiency causes inherited anaemia and has a DNA test — ask for both parents' results before you buy, and test the cat once as a baseline. Ask specifically, because not every breeder screens for all three.

Play: the hour, split into four

An hour of structured play a day, in four sessions of 15 minutes: a wand toy worked like prey, fetch, a puzzle feeder, and a training session for five behaviours. Add a cat wheel if the house allows, and a 15-20 minute leash walk most days. Rotate toys weekly.

Without that outlet the energy goes somewhere: curtains, shelves, water taps, and 3 a.m. sprinting. Two Savannahs raised together are easier than one, but introductions still need two weeks of separation. Enrichment is the single largest line item in keeping this breed well.

Coat, skin and the simple half of the calendar

The short spotted coat has almost no undercoat: a weekly rub with a rubber curry is the whole routine, more in spring. No baths unless genuinely dirty. Ears weekly, teeth three times a week, claws every two weeks — without a 1 m sisal post those claws go into furniture.

Skin is where stress shows: over-grooming on the belly and inner thighs, or bald patches at the flanks, usually tracks a change in routine rather than a parasite. Photograph the patch monthly to see whether it is growing.

The legal and travel calendar

Check the rules before you buy: Australia banned imports in 2008, Hawaii prohibits the breed, and several US states and cities require permits or ban F1-F4 cats. Because the serval is CITES Appendix II, crossing a border can need CITES paperwork, rabies titres and a health certificate within 10 days of travel.

Domestically, most airlines treat hybrids over a set weight as cargo. Build the carrier habit early: leave the carrier out, feed inside it, and practise 20-minute car trips monthly so a vet visit is not the first one.

When to call the vet

Open-mouth breathing, panting at rest, or a sleeping respiratory rate over 30 a minute: same day. Collapse or a stiff, uncoordinated gait after excitement: same day, because both HCM and PK deficiency can present this way. Also book for 24 hours without food, three vomits in 12 hours, blood in stool, or weight loss above 5% in a month.

Six mistakes that make a Savannah impossible

  • Buying before checking local law and landlord rules.
  • Assuming a 3 m hallway counts as exercise.
  • Using insect mesh on windows a 6 kg cat leans on.
  • Switching food in two days and blaming the cat for the diarrhoea.
  • Skipping the 12-month echo because the cat is only a year old.
  • Punishing cupboard raids instead of adding ten minutes of puzzle work.

Start here this month

  1. Measure your tallest climbing route and add shelves until it reaches 2.4 m.
  2. Book the baseline echo and the PK DNA test in one visit.
  3. Set four 15-minute play alarms and log whether they happen.
  4. Order a 1 m sisal post and move one daily meal into a puzzle feeder.

Frequently asked

How much space does a Savannah really need?

More vertical than horizontal. Aim for a continuous climbing route of at least 2.4 m, one high perch per cat, and either a secure catio of 3 x 2 m or daily leash walks. Floor area matters less than having somewhere to run, climb and watch from, because a bored Savannah uses furniture and curtains instead.

Which health tests should a Savannah have?

Three: an echocardiogram from 12 months, repeated every 12-24 months depending on generation; a PRA DNA swab; and a pyruvate kinase deficiency DNA test. Ask for both parents' results before buying, because not every breeder screens for all three, and HCM cannot be ruled out by a DNA test alone.

Why does my Savannah get diarrhoea when I change food?

Digestive sensitivity is common in the breed, and a fast switch is the usual trigger. Move to the new food over 7-10 days, increasing the new proportion by about 10% every two days. If loose stool lasts beyond five days, or there is blood or weight loss, stop the switch and book a visit rather than trying a third food.
