An 11-week-old, domestic shorthair cat was presented for evaluation of a congenital right tarsal deformity. The cat was non-weightbearing lame on the right hindlimb. There was severe tarsal hyperextension and concurrent spasticity/contracture/shortening of the gastrocnemius muscle-tendon. The cat was otherwise healthy. Radiographically there was luxation of the proximal intertarsal joint and talocrural hyperextension. Treatment with 10 mu/kg botulinum toxin A (Botox; Allergan) intramuscular injections directly into the gastrocnemius muscle and passive physiotherapy marginally improved the range of motion in the talocrural joint. Definitive surgical treatment with partial tarsal arthodesis produced an excellent clinical outcome. This case report demonstrates the successful treatment of a severe congenital tarsal abnormality and also documents the first clinical use of botulinum toxin in a feline patient.

Malignant lymphoma in the kidneys of dogs has been considered to carry a uniformly poor prognosis. Long-term remission after medical treatment has not previously been reported. The favourable outcome in this case illustrates the limitations of clinical staging in determining the outcome for individual patients.

An 8-week-old domestic shorthair cat was presented with a history of pollakiuria and polydipsia. No abnormalities were detected during the clinical examination other than the penis could not be extruded from the prepuce. Urine culture demonstrated a growth of E. coli, which was treated with a prolonged course of amoxycillin. The polydipsia resolved and the pollakiuria improved but did not completely abate after antibiotic treatment and the cat had occasional bouts of haematuria. Because of the history of pollakiuria and polydipsia and the ongoing, occasional bouts of haematuria, the cat underwent surgical correction of the congenital phimosis. A small wedge of the dorsal prepuce was removed and the ipsilateral edges of the prepuce were apposed using a simple interrupted pattern. The procedure was quick, easy to perform and led to a resolution of the occasional bouts of haematuria and pollakiuria.
