My cat ate Japanese Stiltgrass. Is it safe or toxic for her?

The chia pet plant is not toxic to cats so if Cid were to ingest / chew on the plant, he should be fine. It would probably be best to not allow Cid to chew / eat the plant to prevent any GI upset. I hope this helps! Please let me know if you have any other questions / concerns and I would be more than happy to help you further.

This plant will cause mild to severe GI signs (vomiting, diarrhea, decreased appetite), the toxicity is considered mild. if Knight is experiencing severe vomiting and lethargy you should take her to the vet to get treated.

The inkcap is not considered a toxic mushroom but could still lead to GI upset such as vomiting or diarrhea. I would recommend removing the mushrooms to avoid any such symptoms. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

The ASPCA list is a reliable source and one that I use in practice. If a plant is toxic it could stay in a separate room since most toxic plants only cause symptoms if ingested, however I wouldn’t recommend having any true lilies in the house since even a small amount of pollen can be toxic and pollen could be carried on clothing.

Grass is good for cats. It helps break down their food and therefore helps cats that vomit frequently due to a sensitive stomach or IBD (inflammatory bowel disease). However if Luna doesn't like to eat the grass, then unfortunately there aren't many options to get her to like it. As an alternative you can offer her an easily digestible diet once she is an adult cat (over the age of 1). I would recommend some good high quality brands such as Royal Canin Gastrointestinal high fiber, Limited ingredient Natural Balance or even Wellness no grain, if she develops any kind of stomach issues in the future.

Roses themselves are not toxic to cats, but the thorns can scratch Queen, and eating the leaves and stems could cause her GI upset. In addition, if there are any pesticides spayed on the roses, those would toxic to her.

At worst, you may see some oral irritation, drooling or stomach upset. The plant contains calcium oxalate crystals which are very irritating. If you've seen no symptoms, they are likely not affected. If it happens again, rinse the mouth with cool water for 10-15 minutes and offer a bland diet in small, frequent amounts until any symptoms resolve.
