Ruby Cat Life has a bigger family behind its name: Ruby, Ruby’s son Loki, and Ruby’s granddaughter Coco. Sharing a family tree makes a lovely introduction, but planning a home for three cats starts with looking at each cat separately.
This guide is a practical planning worksheet, not a report of problems in our household. Try it to answer one question: can each cat reach everyday essentials without having to wait for another cat to move?
Count locations, not just objects
Three bowls lined up on one mat are three objects in one shared feeding area. Several beds beside the same narrow doorway may also depend on a single route. The AAFP and ISFM environmental guidelines recommend distributing key resources across different locations, so cats have choices about where to eat, drink, rest, scratch and use a litter box.
Draw a rough floor plan on paper. Mark food with F, water with W, litter boxes with L and resting places with R. Include doors that are normally closed. Then trace a route from a favourite resting spot to each essential. A route that works only when someone opens a door is not continuously available.
Give meals some space
The 2024 AAFP intercat tension guidelines recommend separating cats during feeding, even when they have a friendly relationship. Depending on the cats and the space, this can mean different rooms or a visual barrier between feeding stations. Avoid assuming that eating side by side proves that every cat is comfortable.
For your next ordinary meal, make a separate note for each cat: where the meal was offered, whether the cat stayed there, and whether another cat approached the bowl. Record what happened rather than labeling one cat “bossy” or “jealous.” Do not change food quantities or prescribed diets just to test the layout. Our food-label worksheet can help you keep the exact products straight.
For three cats, start by planning four litter boxes
The AAFP house-soiling guidance gives a general starting point of one litter box per cat plus one extra, spread across multiple locations. For a three-cat home, that means planning for four. This is a starting point rather than a guarantee: accessibility and the cats’ individual preferences still matter.
On your map, circle boxes that share the same entrance or sit together in one room. Ask whether a cat could reach another box if that route were occupied. Keep toileting areas separate from food and resting areas. If space is tight, use the map to identify a workable additional location before buying another box.
A short observation sheet for each cat
Use one copy per cat over a few ordinary days. These are prompts for your own notes, not a scoring system or a diagnosis.
- Name and date: which cat, and when did you observe?
- Meal: location, interruptions and any change from the usual routine.
- Rest: chosen spot and an available alternative.
- Routes: any doorway where the cat waited, turned back or took a detour.
- One next step: a specific location to review, with a date to check again.
Keep useful existing options available while you review the layout. If you see persistent conflict, a sudden behaviour change or toileting outside the box, discuss it with your veterinarian instead of treating the worksheet as an explanation. Do not force cats to share a space to see whether they will “work it out.”
Start with one practical question
Choose the busiest shared area on your map and ask what alternative each cat has. A useful first improvement may be a better-positioned resource rather than another accessory in the same corner.
