This reminds me of a recent special annual general meeting I attended at one of my buildings. It was an extremely heated meeting discussing the potential introduction of a short-term rental bylaw restriction (barely voted down). People start talking about how AirBnB was affecting their personal hotel business, etc.....
One smart guy stood up and said, "listen, AirBnB, Uber, etc., are disruptive business but not for us a strata corporation to worry about the affects on other business. That is up to the government to deal with."
Your cat situation isn't really a bylaw/restriction topic. You by choice rented to someone who had a cat that damaged your unit and you had to sell in an incredibly difficult time to sell a condo (mid 1990s when the leaky condos became daily news).
The tenants in my basement suite have two cats but I planned ahead. I paid $6 per foot for the flooring in my main part of the house, $1 for the flooring in the basement
