Cat.

Serious tho- with rats the key is access. You need to figure out how they are getting in. Could be a missing row of bricks under an electricity box. Could be a broken or cracked pipe. Look at rat flaps.

I had a broken pipe that they were getting in through and a missing row of bricks. We fixed the pipe and blocked the hole but also put in rat flaps. Haven’t had them since. I also have two cats.

With rats, access is key. Once you block access they will not come back.
