I need to find a large kibble to feed the boys. Both now when they eat the Royal Canin ragdoll kibble swallow it whole then spew back up the whole biscuits. So want to find a larger kibble to feed them that makes them chew. I do feed the dental as treats but read shouldn't feed it to them long term. So wondering what else there is. Did look at the maincoon but presume it would be too rich for them. Any ideas please.
