The practice of trap/neuter and release (TNR) is a well recognised way of dealing with feral cat problems. It is also noteworthy that certain animal rescues take in feral kittens, from operators following their removal, for re-homing where domestication is feasible. It is understood that operators dealing with the removal of feral cats generally seek to capture and use humane injection where such a course of action is deemed necessary, taking account of the particular circumstances and the age and condition of the animals.
This approach accords with the principles set out in section 12 of the Animal Health and Welfare Act 2013 which sets out the principles which seek to protect all animals from cruelty - requiring the avoidance of any unnecessary suffering and the minimisation of suffering. Summary offences under this section of the Act are liable to fines of up to €5,000 and/or imprisonment of up to six months.
