It is! I'd like to get a machine eventually; it's still very sturdy but im not good at keeping the stitch in a straight line lol. They were all over it immediately which made my heart happy, took a day and a half to sew.Is that hand sewn?! Wow, that's a lot of work!
It looks great and your rats are obviously enjoying it!
Mine haven't had a proper double layer so I thought making one would be fun! They do love it! Was going for triple layer but the tiers i made were a lot bigger than I was expecting already lol.That looks great,they seem to love that tiered shape too,mine certainly do
