Best money I've ever spent on my 3....100% positive of that. Also these are hot items that will resell at top dollar.
2 of 3 cats are running out of habit now and we're trained 1st day using temptations cheap treats. Start by just getting them to eat 1 treat off the wheel and another when they get on and from there hold the treats up in front of their faces and hold it up just high enough that they start walking forward. Use a lot of treats 1st few days and you won't need any after.
