10 Best Cat Birthday Party Supplies 2026 in the United States

The SEKAM Cardboard Cat House with Scratcher and Catnip is a well-designed multifunctional item that can be a great addition to a cat birthday party. It serves as both a cozy hideaway and an engaging scratcher, addressing both rest and play needs. Its forest cabin design, complete with a customizable name space, adds a charming touch to the party decor. The spacious dimensions (16.5''L x 12''W x 15''H) and wide entrance ensure comfort for most indoor cats, though it's advisable to measure your cat to ensure a good fit.

The inclusion of a removable corrugated scratcher board and catnip enhances engagement and encourages healthy scratching habits. Assembly is straightforward, requiring no tools, which is convenient for quick setup and storage. Crafted from durable cardboard, it's both lightweight and sturdy, making it easy to move around as needed.

This product is best suited for cat owners looking for a functional and decorative item that can entertain their cat during the party but would need additional items to complete the birthday experience.

The Cat Ladies Cat Grass Growing Kit is a unique addition to a cat birthday party, especially as a healthy treat and fun activity rather than a typical party supply like decorations or costumes. It includes organic seeds, soil, and two stylish ceramic planters that grow edible grass rich in fiber, which helps with your cat’s digestion and hairball control. This kit is low-maintenance and grows quickly indoors with minimal sunlight, making it convenient for any cat owner.

While it doesn't serve as a decoration or entertainment toy directly, it offers a natural and safe treat that can distract cats from harmful plants and keeps them happily nibbling on fresh grass. The ceramic planters also add a cute, natural look to your home, subtly complementing the party environment. However, it doesn’t replace traditional party essentials such as themed decorations, toys, or cat-safe cakes, so you might want to combine it with other items for a full celebration setup.

This kit is ideal for cat owners looking to provide a healthy, organic snack and a little greenery that benefits their cat’s well-being during or after the party.
