Small Black Cat in the Window Halloween Bath Bomb
Our black cat is back at the window for Halloween 2026.
This returning favourite is scented in sweet Toffee Apple and painted to look like the silhouette of a black cat gazing through a window. The dark cat and frame details stand out against hand-painted gold window panes, as though your wee cat is watching fireworks or glowing street lights outside on Halloween night.
Before the bath, the outer bomb appears orange. As soon as it touches the water, the colour transforms into a vivid fluorescent yellow, with little hidden colours tucked into each corner adding extra flashes as it fizzes.
This detailed design is a proper single-bath bomb from our smaller £3.50 range—ideal as an affordable Halloween gift, a Boo Box extra or a recognisable shape for colourful supervised potion play.
Maker Info
These small Halloween bath bombs are moulded and hand-painted in-house at Boddle Bath by Jen or Cheryl-Marie. Each one is handmade in Scotland under our current cosmetic safety assessments using our colourful, skin-kind Boddle formula.
Because every bath bomb is individually made and painted by hand, colours and little finishing details may vary slightly. That is all part of their handmade charm.
How to Store Your Bath Bomb
For the best fizz, fragrance and colour, keep your bath bomb wrapped and store it somewhere cool, dry and away from direct sunlight until you are ready to use it.
Bathrooms can become warm and steamy, so a cupboard or drawer elsewhere in the house is usually better. Avoid displaying the bomb on a bathroom windowsill, as sunlight may fade its colours and moisture can soften it.
Our bath bombs are assessed for use for 12 months after production, but we recommend enjoying yours within 6 months while it is at its fizziest best.

Full ingredient information, including a plain-English guide to what each ingredient does, can be found on our What’s in our bombs? page. The exact ingredients and fragrance allergens for your bath bomb are also printed on its product label.

- Sodium Bicarbonate (baking soda)
- Citric Acid
- Parfum (fragrance oil)
- Prunus Amygdalus Dulcis Oil (sweet almond oil)
- Sodium Lauryl Sulfoacetate (SLSa)
- Polysorbate 80
- Kaolin Clay
- CI colourants, including water-soluble dyes and mica paints
Small Bomb Size & Bath Art
This is a small £3.50 Halloween bath bomb made for one full bath. It is larger than our mini colour bullets but noticeably smaller than our £6 Big Showstopper designs, making it a lovely affordable bath treat, party favour, wee minding or potion-play ingredient.
Our small bombs usually contain one large hidden colour or two smaller half-colour embeds. They will still create a fun burst of colour, but the bath-art display and finished water will be lighter than you would get from a larger showstopper containing several embeds.
Drop the whole bomb into the bath for a colourful single-bath treat, or let children dunk, crumble and crush it during supervised potion play. However they choose to use it, finish running the bath to a safe, comfortable temperature before anyone gets in.
