Preparing Your Home to Foster Cats & Kittens

Why fostering matters

Fostering cats and kittens doesn’t just save lives—it transforms them. When you open your home to a cat in need, you provide a safe space for them to heal and grow. According to the ASPCA, foster homes free up shelter space for other animals, save neonatal kittens who require round‑the‑clock care, introduce cats to new adopters and give foster caregivers companionship and joy¹⁰.

If you’re contemplating becoming a foster parent, the first step is making sure your environment is ready. Cats are sensitive to stress and change, so your preparation will significantly influence their wellbeing.

Create a safe base room

A dedicated, quiet room allows a new foster cat to decompress and feel secure. Animal‑behavior experts emphasize that a private space reduces stress and prevents unsafe hiding adventures¹. Bathrooms, spare bedrooms or laundry rooms with doors that close are ideal choices². Use a baby gate or playpen panels to section off part of a larger room if needed².

Equip the base room with all of the essentials (litter box, food, water, bedding and a scratching surface). Block dangerous hiding spots behind appliances or inside open vents and provide a cozy hideaway like a cardboard box or covered bed so your foster can retreat when nervous³. Offering hiding options has been shown to reduce feline stress and encourage exploration³.

Feline pheromone products can ease the transition. A Feliway Comfort Zone diffuser emits synthetic facial pheromones that mimic the scent cats rub on you when they’re content; studies show these diffusers often help reduce anxiety⁴. Place the diffuser in the base room, follow the manufacturer’s instructions and allow several days for effect.

Cat‑proof your home

Before expanding your foster’s access beyond the base room, thoroughly inspect the rest of the home for hazards. Cats, especially curious kittens, will explore every nook and cranny. Key hazards include exposed electrical cords, small objects that can be swallowed, toxic plants, household cleaners, open windows or toilets, dangling blind cords and unstable shelves⁵. Cover trash cans, close toilet lids, keep food off countertops and remove toxic plants and chemicals⁵.

Consider investing in products that make cat‑proofing easier. Cord protectors such as the Spiral Cable Sleeves shield wires from sharp teeth and claws. Pet playpen panels like the SONGMICS modular playpen can block off areas such as under a bed or behind the refrigerator². Window screens and childproof latches prevent escapes. Stow away fragile décor and drape furniture you don’t want scratched until your foster learns proper scratching behavior⁷.

Essential supplies & gear

Gathering the right equipment ahead of time will help your foster adjust quickly. Animal‑care organizations recommend having bowls, quality food, identification tags, a soft bed, litter box and litter, scratching posts, treats, toys and grooming supplies on hand⁶. Below are some specifics to guide your shopping list.

Introducing your foster to the household

When your foster seems comfortable in their base room—eating, using the litter box and showing curiosity—gradually expand their access. Let the cat set the pace. Open the door and allow them to explore adjacent areas while monitoring for stress. Exchange bedding or toys with resident pets before face‑to‑face meetings so they can learn each other’s scents. Supervise initial introductions and separate at the first sign of fear or aggression. Provide plenty of high perches and hiding spots so your foster feels in control of their environment. Patient, gradual introductions help prevent territorial disputes and build confidence.

Special considerations for kittens vs. adults

Kittens require more frequent feeding, socialization and supervision than adult cats. They are still developing coordination and will climb anything available. Keep them in a smaller, kitten‑proofed space until they are big enough to navigate larger rooms safely. Provide shallow litter boxes and kitten‑sized toys, and schedule multiple play sessions each day to burn off energy. Kittens also need more sleep than adults, so offer cozy bedding. Always wash your hands and sanitize between litters if fostering multiple groups to prevent disease transmission.

Adult cats may take longer to adapt to new environments. They might hide for a few days and will appreciate hidey boxes and vertical space. Use slow movements and quiet voices to build trust, and avoid forcing interactions. Monitor for signs of stress such as hiding, appetite changes or overgrooming, and consult your rescue coordinator if you’re concerned.
