Aquatic turtle

Sheldon is an African musk terrapin, he is fully grown and 8years old. Fully grown he is smaller than the size of my hand. He has not shared a tank since he was less than 1year old so uncertain if he is social with other terrapins. Everything included; tank, filter, lights, heater, raft, pebbles He needs a new home as my cats have become obsessed with trying to catch him, free to a good home
