None of my buisness but if he did rescue work- 4 is a drop in the bucket!
Tell him your goal is 40, that way 2 more is no big deal!! (is that manipulative- no, just the facts!) Anyone that has less than me, needs more! (poor me and litter in the bed and cat hair on my clothes etc)...Misery loves company! And what's litter, cat hair (oh and that poop odor pretty much all the time) compared to being homeless, jobless, lonely, dispaired and depressed? I figure we all go through some pretty bad times and the more kitties- the better the outcome- motivates me to keep on keeping on many times over the last 20+ years!
