We have a 10 year old dog Lab/Spaniel Mix and 3 cats under the age of 3,,,,They were strays rescued by my daughter...Apparently the Bob Evans restaurant she works at is a popular cat dumping place,,,So we said. "Sure, bring them home. As long as YOU take care of them." That lasted all of 3 weeks and now Mrs. Lew and I take care of them...
All four of the critters get along and the cats, esp the calico, will groom the dog..It is funny to watch and the dog loves it...She just lays there and gets a nice bath as it were...
And these cats will 'fetch' also....They will fetch wadded pieces of paper and that is a fun game...
Now if I can get the cats to eat that noisy bird we have , I'd be all set...Damn thing chirps ALL the time....
