Cat vocalizes to communicate with another and express their internal states. The vocal repertoire of the cat is wide and up to 21 different vocalizations have been described in the literatures. But it is more than probable that the repertoire contains more types of vocalizations. An ethogram was created in this paper describing the actual known vocalisations of the domestic cat based on an auditory classification. However, the audiogram allows also a visual classification which can increase the accuracy of vocalization differentiation. The classification can be risky as it is sometimes unclear if different types of vocalizations are produced in different environments or if a unique type of vocalization is used with variation in the acoustic parameters. As an example, isolation calls produced by kittens differ depending on the context. The environment has an important impact on the vocal behaviour and thus feral cats and pet cats vocalize differently. Pet cats are thus able to create an efficient communication with humans thanks to the flexibility of vocalisation behaviours. This review allowed us to create a simple model of the cat vocal repertory.

Cryopreservation of epididymal sperm is an effective technique to preserve genetic materials of domestic cats and wild felids when they unexpectedly die. However, this technique inevitably causes detrimental changes of cryopreserved-thawed spermatozoa, for example, by physical damage and excessive oxidative stress. L-carnitine is an antioxidant that has been used to improve sperm motility in humans and domestic animals. This study aimed to investigate the effects of L-carnitine on cat epididymal sperm quality following cryopreservation and thawing. After routine castration, cauda epididymides were collected from 60 cat testes. The epididymal spermatozoa from 3 cauda epididymides were pooled as 1 replicate. Spermatozoa samples (16 replicates) were examined for spermatozoa quality and then randomly divided into 4 groups: 0 mM L-carnitine (control), 12.5 mM, 25 mM and 50 mM L-carnitine. The sperm aliquots were then equilibrated and conventionally frozen. After thawing, sperm motility, plasma membrane integrity, DNA integrity and acrosome integrity were evaluated. The 25 mM L-carnitine significantly improved sperm motility compared with a control group (p<0.05), although this was not significantly different among other concentrations. In conclusion, supplementation of 25 mM L-carnitine in freezing extender improves cauda epididymal spermatozoa motility. The effects of L-carnitine on the levels of oxidative stress during freezing and thawing remains to be examined.

A 2-year-old female Persian cat weighing 2.95 kg was admitted for dystocia. The levels of white blood cells and thrombocytes were decreased in blood analysis. In radiography and ultrasonography, there were four fetuses with no remarkable signs of blood flow and heartbeat. In particular, one of them showed symptom of Spalding's sign, which is a rare symptom that indicated overriding of the fetal cranial bones and shrinkage of the head with a decreased volume. It was reported that Spalding's sign is one of the strong indication of fetal death in human uterus and it occurs rarely with normal fetus without apparent reason prior to labor in human. This is the first report to provide the Spalding's sign in domestic cats and this will be applied in a strong presumptive evidence that fetal death has occurred with brain disruption sequence while pregnancy in domestic animals.

A 1.2 kg, five-month-old, female domestic short-hair cat was referred to Seoul National University Veterinary Medical Teaching Hospital with a history of vomiting immediatley after eating. Clinical signs were depression, anorexia, severe dehydration and vomiting since weaning. According to history taking, physical examination, complete blood count, serum chemical profile and contrast radiographic study, it was diagnosed as congenital sliding esophageal hiatal hernia. Diaphragmatic plication, esophagopexy and left-sided belt-loop gastropexy were performed. Ranitidine (2 mg/kg, IV, q12h) and sucralfate suspension (20 mg/kg, PO, q6h) were administered with low-fat liquified diet to treat reflux esophagitis. Clinical signs related to esophageal hiatal hernia disappeared immediately after surgical treatment and did not recur for 4 months.

A 6-year-old male domestic shorthair cat was referred to Gyeongsang National University Animal Medical Center for labored breathing. According to the patient's history, the client had fed him commercial dog foods. The patient's hematological, radiographic, and echocardiographic examinations were evaluated for diagnosis. Echocardiography results showed marked dilations of ventricles and atriums and mitral regurgitation. A systolic dysfunction was detected. Plasma taurine concentration was lower than the reference range. Based on these results, the patient was diagnosed with feline dilated cardiomyopathy associated with taurine deficiency. Treatment included feline commercial foods, taurine, digoxin, furosemide, and clopidogrel. Digoxin was changed to pimobendan when normal blood pressure was achieved. Clinical signs improved gradually and no abnormalities were detected on echocardiograms at 10 weeks following onset of treatment.

A 2 months old female Korean domestic shorthair cat weighing 1.2 kg was come to hospital because of respiratory discomfort and lethargy. Heart sounds was more intense and clear on the right side than the left. On radiographic views, loss of the normal diaphragm line, undistinguishable shadow of heart, shadow of gas-containing intestines could be observed in thoracic cavity. Diaphragmatic herniorrhaphy was performed by using propofol 8 mg/kg IV and isoflurane without any complication. On 7th day after the operation, almost all the clinical signs and radiographs including diaphragmatic line, cardiac silhouette, liver and small intestines were turned to normal.

A 7-year-old neutered male, domestic shorthair cat presented anorexia and lethargy. The complete blood cell count revealed severe non-regenerative anemia, lymphocytic leukocytosis, neutropenia, and thrombocytopenia. On the peripheral blood smear examination, medium to large lymphoblastic cells with moderate amounts of basophilic cytoplasm were observed in up to 70% of peripheral leukocytes. Feline leukemia and immunodeficiency viruses were not detected using a commercial diagnostic kit. While splenomegaly and blunt margins of the caudoventral liver were observed in abdominal radiography, changes in the intra-abdominal lymph nodes were not remarkable. Ultimately, flow cytometric immunophenotyping from the peripheral blood revealed a negative for B-cell markers (CD21-/CD79a-) and T-cell markers (CD3-/CD4-/CD5-/CD8-). Based on the hematological examination and the immunophenotyping assay, the cat was diagnosed with non-B, non-T acute lymphoblastic leukemia. Here, we report a rare case of non-B, non-T acute lymphoblastic leukemia to raise awareness and provide information on clinical symptoms and laboratory test and immunophenotyping analysis results.

An 11-year-old neutered male domestic short-haired cat presented with neurological symptoms that developed over a three-month period. These included mental dullness, vocalization, ataxia, and visual impairment. The patient was diagnosed with a primary intracranial tumor at a local animal hospital. After the first diagnosis, the cat was administered hydroxyurea, prednisolone, omeprazole, and gabapentin for 3 months. After the initiation of medical treatment, the patient's clinical symptoms did not improve and the size of the tumor was static on the second magnetic resonance imaging (MRI). The dosage of hydroxyurea and prednisolone was increased for two weeks. The patient's clinical signs improved, and subsequently, a craniotomy was performed. The clinical signs completely resolved six days after surgery. Adjuvant chemotherapy with hydroxyurea was continuously administered after the craniotomy. The patient demonstrated a good clinical status during the nine-month follow-up period. Neoadjuvant chemotherapy has not yet been reported for meningiomas in cats. Further clinical trials with longer follow-up periods and larger patient cohorts will be required to confirm the effectiveness of neoadjuvant chemotherapy with hydroxyurea in feline meningioma.
