Some chins use the hammocks, others don't. Some don't want me to know they use their hammocks, I guess, cause I never see them in them. But the poos tell another story. ALL of the chins who have ever had fleece tubes have loved them. They have been a hit with all the chins. The hammocks... some chins love them, some can take it or leave it. Some chins seem to need time to get used to the idea that they move, and then they like them... but others.. we had one chin that literally lived in his hammock. He'd get out to eat, drink, and run around a bit, and then right back to the hammock. Depends on the chin I think.
