There's a row about officials in Aberdeen trapping and killing grey squirrels to protect their red relatives. Here's what children in Aberdeen had to say about it...
The traps were set up because experts said the greys were eating the reds' food. Andrew, 10: "I think the greys should be killed to give the reds a better chance of living."
Greys are bigger and more aggressive than their red relatives. Bethany, 11, said: "I think it's OK to kill some of the grey ones just to protect the reds."
Animal rights groups have hit out at the cull, saying it's cruel. Rachel, nine, said: "I think it's mean to kill the squirrels because at the end of the day, they are both just squirrels."
Greys also carry diseases which can kill reds. Matthew, nine, said: "I think we should use some money to buy food for the red ones so we don't have to kill the grey squirrels."
The greys aren't native to the UK. They came over from America more than 100 years ago. Jodi, 10, said: "The reds should stay here because they were here first."
Greys have squeezed out the reds in many areas. Cameron, 11, said: "I don't think humans should interfere with evolution. We should just leave the red and greys to live their lives."
