Tabby cat urns, sized to them.
Most cats weigh 3.6 to 5.4 kg (8 to 12 lb), so a tabby cat needs about 195 to 265 ml (12 to 16 cubic inches) of space. Our minimalist cat urn holds a cat up to 5.5 kg (12 lb), and our seated cat urn is sized to your own cat's weight.
We sculpt each of our photo urns from your cat's own photos, so it is a likeness of them, not a breed model. Enter their weight below to check the size.

Choosing for a tabby cat, answered plainly.
What size urn does a tabby cat need?
Most cats weigh 3.6 to 5.4 kg (8 to 12 lb), so a tabby cat needs about 195 to 265 ml (12 to 16 cubic inches) of space. Our minimalist cat urn holds a cat up to 5.5 kg (12 lb), and our seated cat urn is sized to your own cat's weight.
Allow one cubic inch of space for each pound they weighed when they were well, plus a tenth, plus 3 cubic inches. Use your cat's own weight, not the breed's: your vet will have a record of it. If they were close to the top of a size, choose the next one up.
Can you make an urn that looks like my cat?
Yes. We sculpt it from your photos of them, so it shows your cat, not a stock figure.
Send a few clear photos and we design it for free; you pay nothing until you say yes to the design. Making takes 10 working days from your yes.
Which of your cat urns should I choose?
Our minimalist cat urn holds a cat up to 5.5 kg (12 lb), which fits most cats. For a bigger cat, choose our seated cat urn: we size it to your cat's weight.
Our other photo urns hold a pet up to 15 kg (33 lb) in Small.
Can the urn go outdoors?
Yes: the stone takes rain and frost.
The urn does not seal out rain, so the ashes stay in their sealed bag inside it.
