NIL was my limit , because of my allergy to cats, I guess not being able to say no to my daughter was the reason Ash eventually became adopted, and most of you know the rest, now I am a happy two cat household, however I would like at least one more, but I have to be sensible about it, and not put the two I have already in jeopardy, as financially that is my limit, and allergy wise probably as well, but hey I am fortunate to have the two I have and count my blessings every single day.
