Its evaluation is crucial for assessing patient health. In cats, liver disorders often alter organ size and structure. Abdominal ultrasound is a safe and widely accessible tool in veterinary practice, and it is key to assessing liver morphology, although its interpretation remains subjective. This study aimed to establish a standardized method for measuring the liver of cats and determine reference values for healthy young and adult animals. Clinically healthy cats without laboratory or ultrasound signs of hepatobiliary disease were included. Radiographic parameters from the literature were applied to confirm normal liver dimensions. The cats were divided into two groups according to their body condition scores: 20 with an ideal weight (Group 1) and 20 that were overweight or obese (Group 2). Standardized planes were defined for the left and right hepatic lobes. Measurements were taken three times per lobe to calculate the mean distance from the diaphragmatic surface to the caudal border of the liver. Groups 1 and 2 did not differ significantly in their results. However, males presented higher overall mean values than females, and the left lobe was consistently longer than the right lobe. The established reference values were based on sex and lobe: in males, left lobe 3.46 ± 1.23 cm, right lobe 2.80 ± 0.88 cm; in females, left lobe 3.12 ± 1.05 cm, right lobe 2.57 ± 0.97 cm.

This report describes three clinically distinct cases of microfilaruria in companion animals from Kerala, India, an endemic region for canine filariasis. Case 1 involved a dog with dual infection by morphologically identified <em>Dirofilaria repens</em> and <em>Brugia</em> spp., associated with hemorrhagic cystitis and hypermicrofilaremia. Case 2 involved a diabetic dog with <em>E. coli</em> urinary tract infection, in which microfilariae were detected in the urine sediment, likely due to glycosuria-induced epithelial compromise. This represents the first documented case of microfilaruria in a dog with concurrent diabetes mellitus. Case 3 documented the first reported occurrence of microfilaruria due to <em>D. repens</em> in a cat, which was likely triggered by trauma-induced urethral obstruction. All cases were managed with targeted therapy based on the primary diagnosis, combining anthelmintics, antibiotics, supportive care, and metabolic regulation. These cases suggest that microfilaruria may occur via various mechanisms, including inflammation-induced uroepithelial disruption, glomerular leakage, or local trauma. Molecular confirmation (e.g., PCR) was not performed; hence, definitive differentiation between <em>D. repens</em> and <em>D. asiatica</em> was challenging and represents a limitation of this study. The paper emphasizes the critical importance of routine, thorough urine sediment examination, even in atypical species like cats, and in animals with concurrent systemic or metabolic disorders.

Between November 2024 and March 2025, blood samples were collected from 100 clinically healthy dogs (72 from Beberibe and 28 from Cascavel). Diagnostic testing included immunochromatographic assays for <em>D. immitis</em> antigens and microscopic evaluation for circulating microfilariae.

Twenty healthy dogs were randomly allocated to the FM group (free meloxicam - 0.2 mg/kg) or to the MNano group (meloxicam loaded-nanocapsules - 0.2 mg/kg).

Platelet function was measured through a buccal mucosal bleeding time test before meloxicam administration, four hours after that administration, at the end of the OH, and 12 hours after taking the medication. In addition, creatinine was measured preoperatively, 24 and 48 hours after meloxicam administration. The distribution of rescue analgesia in the intraoperative period showed no difference between groups. No patient required supplemental analgesia in the postoperative period.
