I am pretty sure that they were checked for worms at each of their check ups last yr. It is coming time for their rabies shots so I guess that I will ask the vet then.
My older cat is 15 months old and the younger one will be a year old March 19 and they are both eating dry cat food.
Happy6, I will check out that web site to see if I can find out something there in the meantime.
Thanks everyone!
I forgot to add that they are strictly indoor cats and not outside so I don't think that they would've picked anything up that way.
