Chocolate is toxic to cats. While rarely fatal, chocolate ingestion can result in significant illness. It contains theobromine and caffeine, which cause clinical signs such as an increase in heart rate, blood pressure, agitation, tremors, and seizures. Signs of chocolate poisoning can take several hours to develop and can last for several days.

Cholecalciferol is one of three main active ingredients found in rodenticides. It is commonly found as a soft bait and occasionally as a hard block or pellet. While it may seem like a safer option than anticoagulants, there is no antidote available and the amount in a single block is enough to cause a severe overdose in nearly all animals.

Chondrosarcomas arise from cartilage, which is a connective tissue primarily found where bones meet with joints, as well as at other locations in the body such as the nasal cavity, and ribs. Chondrosarcoma is a rare tumor in cats, but it can occur. Clinical signs of chondrosarcoma may vary significantly, depending on where the tumor arises. Although the mass may grow rapidly, less than 20% of feline chondrosarcoma cases metastasize to other parts of the body. Therefore, surgical removal is curative in many cases.

Chondrosarcomas arise from cartilage, which is a connective tissue primarily found where bones meet with joints, as well as at other locations in the body such as the nasal cavity, and ribs. Chondrosarcoma is the second-most common primary bone tumor in dogs. Canine chondrosarcoma most commonly affects the flat bones of the body, such as the ribs, skull, nasal cavity, and pelvis, although the limbs can also be affected. Aggressive surgical removal is typically recommended, although radiation therapy may also be used, depending on location of tumor. Metastasis may occur but is relatively uncommon.
