A. Many plants can be poisonous to cats, so if you know the type of plant eaten it is best to look up if it is safe for your cat to do so. If you suspect the plant is toxic, it is best to contact your local vet for care.
Loose stools in cats can be caused by a number of things ranging from chronic stress, internal parasites, food allergies, to digestive upset and internal illness. You can try some home remedies such as adding pureed pumpkin or plain yogurt to meals which may help bulk up the stool some and is safe for your other healthy cats to ingest.
However if the loose stools continue, bringing in your cat as well as a sample of his stool to your vet is best. They can check for any internal parasites which may be causing the issue, as well as look for any underlying conditions causing it. If a food allergy is the cause, changing the food should be fine for your other cats if they are healthy.
