I understand completely about life getting in the way sometimes. I hope your kitty is getting better. We have three cats and know they sometimes need your attention more than music. What I try to do is, unless it is completely impossible, practice for just 10 minutes on those days that are hectic. If you really can’t even do that, don’t worry about it! If you are like me, you are learning to play because you love music and you love the violin (or any other instrument). The main thing is not to give up altogether! You may be surprised at how much you can do in 10 minutes. Then, when things simmer down and you can practice longer, take advantage of it.
