Ar 12 Rhagfyr 2017 cyhoeddais Ddatganiad Ysgrifenedig fod Llywodraeth Cymru wedi cytuno â  Llywodraeth y DU y dylai ddeddfu ar gyfer Cymru a Lloegr i gynyddu’r ddedfryd lymaf am greulondeb i anifeiliaid o chwe mis i bum mlynedd. Dylai’r rheini sy’n euog o achosi’r creulondeb mwyaf i anifeiliaid ddioddef cosbau llym, ac mae’n bwysig cadw trefn ddedfrydu gyson ar draws Cymru a Lloegr gan sicrhau eglurder i’r asiantaethau gorfodi, y Llysoedd a’r cyhoedd.
On 12 December 2017, I issued a Written Statement on the Welsh Government agreeing to the UK Parliament legislating by Act for England and Wales to increase the maximum sentence for animal cruelty offences from six months to five years. Those who commit the worst acts of animal cruelty should face tough punishments and maintaining a comparative sentencing regime across England and Wales is important to ensure clarity for enforcement agencies, the Courts and the public.
