So I had a Cat in my bank and now it has disappeared. I've tried the call follower option and it says I have no followers. I've also went to gertrude to buy another but she just gives me the same dialogue about starting the ratcatchers quest, even after I agreed to start it. I've also went and died in game to make sure that wasn't the issue. I've reached out to jagex but do any of you know anything about this?

Finish ratcatchers and her dumb dialogue will go away and you can get cats again.

Is there a cat or kitten in bank? Did you try the search feature in bank? May have become an overgrown cat

can I finish ratcatchers without a cat?

I believe you just right click her and click kitten to get another.

You can but the time it takes to do ratcatchers as a kitten is rediculous. Might as well afk 3 hrs get a cat then do it
