Rope toys that don't unravel easily?

@Sha I haven't had very good luck with rope toys unraveling. Merlin is very good at pretty much destroying them in a fairly short amount of time. That being said, I just bought him a new one recently that has a rubber spiral with the rope toy inside it. I'll let you know how that works out! (I like it because it's smaller than the others I've gotten him so far.)

I have that problem with my guys too, I don't know if Merlin does this but my guys like to pick and pull at the ropes.
I usually find that the ropes that are bigger then them last longer because I think there more tightly woven together then some of the smaller ones. I even tried one of those rope balls but it didn't take long for Sawyer to ruin it. I forget what brand they are but I normally get the biggest one from Walmart which are 5 knots (I just looked around online and I'm pretty sure there the mammoth brand). Not to say that they still don't eventually get a bit ratty but the last a bit longer/hold up.
I would say try something a bigger then what you would normally get for his size and look for ropes that have a tighter weave (basicly were you cant easily pull the sections apart).

So Pax has those exact toys...once he pulls them apart, I disassemble all the ropes, discard the "head", and tie a bunch of the strands together in a knot at the top and tie a single knot at the end of each stand and he loves it just as much.

The knots at the ends of teach stand keep the fibers from fraying. Turns it into a rope octopus and those become our tug toys.

If she is not chewing the head off, just start by tying a knot in the end of each strand and let it unravel.

I'd dare to say this is near impossible....
