Article Abstract

The aim of this study was to examine the effect of the suckling period length (SPL) on weight status among adult cats while taking into account putative risk factors. To this end, the body fat percentage of 69 client-owned cats was determined. A body fat percentage of >30% was used for overweight classification. Cat owners were interviewed using a standardised questionnaire to collect information about the SPL, age, breed, sex, feeding amount and frequency, daily playing and outdoor access. SPL was categorized into four groups (0-6, 7-11, 12-16, 17-24 weeks). Logistic regression was used to estimate the association between overweight and SPL after adjusting for identified risk factors. Of the 69 cats, 37 were overweight. The odds for overweight was three times lower in cats with a SPL > 6 weeks (OR = 0.33, 95% CI = 0.10-0.99). This study identified a possible novel, modifiable early life risk factor for overweight in cats; the SPL. The results of this study indicate that allowing cats to nurse longer than 12 weeks might be a simple intervention to improve cat health and welfare.

Introduction: Injuries sustained by animals are now common. A review of cases shows that injuries usually manifest as penetrating injuries, lacerations, crushing and tissue rupture. These can lead to severe complications, including infection, deformity, zoonotic diseases and, in extreme cases, death.

Hepatozoon felis is a protozoan parasite reported in Europe, Africa, Asia and the Americas with infection rates ranging from 4% to 30% in domestic cats in Mediterranean countries. Although the parasite was described in 1908, its arthropod vector has not been reported to date. Ticks removed from cats were dissected to prepare hemocoel smears with the aim of identifying the sporogonic life stages of H.

ObjectivesThe aim of the present study was to evaluate the sedative and echocardiographic effects of dexmedetomidine (DEX) administered via intranasal (IN) and intramuscular (IM) routes in cats.MethodsThis randomised, blinded crossover study involved eight healthy adult cats. Cats were randomly allocated to receive DEX 10 μg/kg via either the IN or IM routes.

ObjectivesHistorically, vaccines have been administered in the dorsal interscapular region of cats (the 'scruff' of the neck) owing to easy access to the subcutaneous space. In response to concerns about sarcomas developing at injection sites (feline injection site sarcomas [FISSs]), and a possible association between feline leukaemia virus (FeLV) vaccination and the development of FISS, alternative FeLV vaccination sites such as the distal left hindlimb and tail have been proposed by influential vaccination bodies and various key opinion leaders. There is a dearth of evidence, however, to demonstrate the development of a comparable immune response after FeLV vaccination in these sites.

Hereditary adult-onset ataxias are a heterogeneous group of phenotypically overlapping conditions, often caused by pathogenic expansions of short tandem repeats. Currently, 18 repeat disorders with a core phenotype of adult-onset ataxia are known. Diagnosis typically relies on sequential PCR-based methods, which are labour-intensive and lack precision.
