Should I wait and see, or take action now and figure out a different location for the fermenter? I could try convincing the wife to put it in her office. Not sure how well that'd go down, though.
Cats or not cats, I think it'll be fine! I have a big yellow lab, a cat, a grandson, etc, and so far I've not had any problems.
The best way to figure fermentation temperature is to just look at the yeast maker's website. I assumed you were using Wyeast London ale yeast, which says:
YEAST STRAIN: 1028 | London Ale™
Back to Yeast Strain List
A rich, minerally profile that is bold and crisp with some fruitiness. Often used for higher gravity ales and when a high level of attenuation is desired.
Temperature Range: 60-72F, 15-22C
So, you can see you're within two degrees of the yeast strain's optimum range so I think you'll be fine!
A couple of points, though- first, you should always make a starter for liquid yeast because you're probably underpitching the yeast (I know, I know, the package says it's enough- but it's really not), and although I never usually recommend this, you can pitch when your wort is warmer, before it cools down so much after the boil. Say you pitched the yeast when the wort was at 65- that would help the yeast replicate before cooling down to 58. That's not the ideal way to do it, but if you don't have a way to keep the beer above 60 degrees before fermentation takes off, that would work.
Also, do you have a "stick on" thermometer, like for an aquarium? That would tell you the temperature of the beer, not the ambient and that is the most crucial.
