Hey all... we now have 5 stray cats (2 adults & 3, 5 mo old kittens... we had 0 cats as of last April... HELP!) & I'm looking for some inexpensive ways to get some extra weight on them as we live in Michigan & winter is fast approaching (supposed to be 32 degrees Sat. night!)... I am feeding dry (costco) & wet (friskies) unfortunately, I am on a pretty tite budget (arn't we all?) so need to keep the costs down... any ideas would be great!
