Leptospirosis is a zoonotic disease with a worldwide distribution affecting most mammalian species. Clinical leptospirosis is common in dogs but appears to be rare in cats. Both dogs and cats, however, can shed leptospires in the urine. This is problematic as it can lead to exposure of humans. The control of leptospirosis, therefore, is important not only from an animal but also from a public health perspective. The aim of this consensus statement is to raise awareness of leptospirosis and to outline the current knowledge on the epidemiology, clinical features, diagnostic tools, prevention and treatment measures relevant to canine and feline leptospirosis in Europe.

A randomised, single-blinded, positively controlled, field trial for weight loss in obese client-owned cats was undertaken to look at novel diets and dietary strategies that could improve owner compliance and, therefore, success of feline weight loss programmes. Three dietary strategies were evaluated: strategy A used a novel dry high fibre ration; strategy B used ready-prepared portions of dry and moist food; strategy C used an existing commercial dry high fibre ration fed with a measuring cup. Cats were assessed at weeks 4, 12 and 20, and adjustments to the energy allocation made if required. Mean weight loss at 20 weeks (A: 11.0±1.3%, B: 10.9±1.2%, C: 11.9±1.7%) and mean energy allocation (A: 31.0, B: 28.5 and C: 32.2 kcal/kg of target body weight/day) were similar amongst strategies. However, owners' subjective hunger score was significantly ( P<0.001) higher with strategy C than with strategies A and B. Further, owner satisfaction was lowest with strategy C, and more owners also regarded food allowance as insufficient with this strategy. Novel diets and feeding strategies may improve outcome in feline weight loss programmes.

The incidence of catheter-associated urinary tract infections in cats catheterised for an obstructive lower urinary tract disease (LUTD) has not previously been evaluated. The objective of this study was to evaluate the frequency of significant bacteriuria in cats with obstructive LUTD managed for 48 h with a closed urine collection system. Eighteen male cats admitted for a non-infectious obstructive LUTD were evaluated. This was a prospective study. A standard protocol was used for aseptic catheter placement and maintenance. Three urine samples were collected from each animal through the catheter immediately after placement, 24 h after placement and just before removal. All samples underwent complete urinalysis, including bacterial culture. Catheter tips were tested by bacterial culture. Six cats (33.3%) developed significant bacteriuria during catheterisation. The causative bacteria were common feline uropathogens ( Escherichia coli, Staphylococcus species) in five cases, and Streptococcus bovis in one. One cat developed a fungal infection. The presence of bacteria in urinary sediment was correlated strongly with positive urine culture results. The catheter tips from 10/18 cats (55.5%) were positive for culture. The positive predictive value of a positive culture from the urinary catheter tip was 87.5%. The specificity was 53.8%. The same infectious agents were cultured from both urine and catheter tip in six cases. In summary, one-third of cats developed significant bacteriuria during catheterisation. Silent bacteriuria could not be clearly differentiated from true urinary tract infection. The presence of bacteria in the urinary sediment was strongly indicative of bacteriuria. The specificity of urinary catheter tip culture was low.
