2 cats missing clondalkin

My two cats, male and female missing within days of each other. The first is a male 3 year old neutered. He is a grey and white tabby cat. He is very loving to the family but not a very friendly cat. He is not as big as a full grown tom cat. He also has a scar/wound on his foot. The other is a 9 year old black and white female. She would not appear to be an old cat as she is very healthy. She is a large cat. She would not wander very far from the house. She is spayed. Please help keep a look out for them or contact me if they are found as it is over a week, I really want to find them as they are family pets.
