Is it bad if a domesticate house cat eats one grass seed from the store?

It's unlikely that a single grass seed from the store will cause any serious harm to a cat. However, here's why it's good to be cautious:

* Digestive Issues: While a single seed is probably fine, ingesting a larger quantity could cause stomach upset, vomiting, or constipation.

* Potential for Obstruction: If the seed is large or sharp, it could potentially cause an obstruction in the cat's digestive tract. This is more likely with seeds that are swallowed whole.

* Grasses & Cats: While some grasses are safe for cats, others can be toxic. You'll want to be sure that the seed is from a species known to be safe for cats.

What to do if your cat eats a grass seed:

* Observe your cat: Watch for any signs of illness like vomiting, diarrhea, lethargy, or loss of appetite.

* Contact your veterinarian: If you're concerned, it's best to contact your veterinarian for advice.

* Prevention: To prevent future ingestion, store grass seeds out of reach of your cat.

Bottom line: A single grass seed is unlikely to cause harm, but it's best to be cautious and keep an eye on your cat. If you're ever concerned, don't hesitate to reach out to your veterinarian.
