Not to be rude or anything, but I just want to spread some awareness that pet toys made from yarn can be dangerous for your pet, as discussed in the community here.
Some people consider them safe but as stated in the post, you should be somewhat careful with this. Maybe you want to give it a thought if you want to include “cat toy” in the title of your pattern once it is ready for publication. I guess we all want our pets to be safe.
Your pattern still seems like a cute goldfish though :)
