The cat may be wheezing and retching due to a respiratory issue such as asthma or an upper respiratory infection. Other potential causes could include hairballs, allergies, or ingestion of a foreign object. It is important to monitor the cat's symptoms and behavior, and seek veterinary care if the wheezing and retching persist or worsen. **

Brownish expectoration after retching can indicate the presence of blood in the vomit. This could be due to a variety of reasons such as a tear in the esophagus, stomach ulcers, or inflammation of the stomach lining. It is important to seek medical attention if you are experiencing this symptom, as it could be a sign of a more serious underlying condition that needs to be addressed. **

A moth is a type of insect that is often referred to as a "night butterfly" due to its similar appearance and behavior to butterflies. Moths are known for being active at night and are attracted to light sources. They have a similar life cycle to butterflies, going through stages of egg, larva (caterpillar), pupa, and adult. Moths come in a wide variety of shapes, sizes, and colors, and can be found in diverse habitats around the world. **

It is likely that a moth is in the room. Moths are typically more active at night and are attracted to light sources, which may lead them into indoor spaces. Night butterflies, on the other hand, are not a commonly recognized type of insect and are not typically found indoors. Therefore, the insect in the room is more likely to be a moth. **

Nausea is a feeling of unease or discomfort in the stomach that often precedes vomiting. It can be accompanied by symptoms such as dizziness, sweating, and a general feeling of being unwell. Retching, on the other hand, is the act of attempting to vomit without actually expelling any stomach contents. It is often characterized by the rhythmic contraction of the abdominal muscles and can be accompanied by a gagging sensation. Both symptoms are commonly associated with gastrointestinal issues, motion sickness, pregnancy, and certain medical conditions. **

The Lime Hawk-moth is a type of moth. Moths and butterflies both belong to the order Lepidoptera, but they have some distinct differences. Moths typically have thicker bodies, feathery antennae, and are active at night, while butterflies have slender bodies, clubbed antennae, and are active during the day. **

There are a few potential reasons why your cat may be wheezing and retching but not vomiting. It could be due to hairballs, which can cause coughing and retching as the cat tries to expel the hairball. Another possibility is feline asthma, which can cause wheezing and coughing but may not always result in vomiting. Additionally, respiratory infections or allergies could also be causing these symptoms. It's important to monitor your cat's condition and consult with a veterinarian to determine the underlying cause and appropriate treatment. **

The term "night butterfly" is not commonly used in English, and the correct term for the insect in question is a moth. Moths are a type of insect belonging to the order Lepidoptera, just like butterflies. However, moths are typically active at night, while butterflies are active during the day. Therefore, if an insect is active at night, it is most likely a moth rather than a butterfly. **
