Speying and castration involves removing the reproductive organs. In females it is the removal of the ovaries and, usually, the uterus. In males it is the removal of the testes. We recommend neutering dogs and cats from 5-6 months. In the case of bitches, if they have already had a season, then neutering is best done 3 months after the season ends.
Female cats will nearly always be routinely neutered. It is of course possible to let a female have a litter and then carry this out afterwards. However it should be remembered that it is not always possible to find homes for the kittens and there are often unwanted kittens and cats that need good homes. If female cats were left un-neutered they would continue having two litters a year for life
Male cats should also be routinely neutered to prevent their fighting and wandering tendencies which inevitably lead to either early death or injury by road accidents or from diseases contracted from their life style. Urine marking with its strong odour is also avoided.
Bitches are usually neutered as it significantly reduce the chances of mammary tumours later in life and avoids the occurrence of infection of the uterus (pyometra) to avoid the continued problem of their seasons which occur twice yearly and also to avoid ‘false pregnancy’ which often occurs 6-8 weeks after the season. Early neutering will .
Male dogs are most often neutered to avoid behavioural problems such as aggression, wandering and urine marking.
Please do not hesitate to ask for advice on this subject if you have any concerns. The operations involved (castration and ovariohysterectomy) require a general anaesthetic. Hysterectomy is of course a more major surgery and although occasional problems can be encountered the procedure is usually routinely straightforward.
One question many owners ask is whether animals put on weight following neutering. While there is no medical reason for this , their energy needs are lower so they should be fed less food.
