No. Cats who bat slime around and groom their paws swallow glue, borax, and glitter that irritate the stomach.

Why it’s a problem

Cats rarely eat slime deliberately, but they are the perfect delivery system for it: a cat pounces on a bright blob, walks through it, and then grooms the glue, borax, and glitter off her paws over the following hours. That creates a low-dose, repeated ingestion of irritants rather than one big swallow. Putty stuck to fur also causes matting and skin irritation if it is not removed gently.

How to keep your pet safe

Keep slime and putty in lidded containers in a closed bin, and clean floor blobs immediately after craft time. Sweep glitter and dried flakes before the cat’s next patrol. If putty gets on fur, work it out with a little dish soap and water rather than letting her chew it free.

Warning signs to watch for

Drooling, vomiting, diarrhea, sticky or glittery fur, paw irritation, refusal to eat, lethargy; repeated vomiting or no stool over days suggests a blockage from swallowed material.

When to call the vet

Wash residue off paws and fur with mild soap and water, then call your veterinarian or a pet poison hotline with the product ingredients. Do not induce vomiting without professional direction. Monitor her appetite and litter box for two days and seek care for repeated vomiting or no stool.

Common questions

My cat walked through slime and has been licking her paws — is she poisoned?

She is swallowing glue and borax with each lick, so wash her paws now with mild soap and water. Call your veterinarian or a pet poison hotline to assess whether the amount she groomed off needs follow-up.

My cat ate a small piece of putty — is the salt a problem for her too?

A small piece is unlikely to cause salt poisoning in a cat, but it can still upset her stomach. Call your vet or a pet poison hotline with the amount and watch her for a day.

How do I get dried slime out of my cat’s fur?

Soften it with lukewarm water and a little dish soap and work it out gently, trimming only if needed. Keep her from chewing it out, and call your vet if the skin underneath looks sore.
