[nagdu] tennis balls

[Julie J]

Does anyone know someplace where I can order the large size tennis balls at a reasonable price?  I've seen them at a pet store a long while ago.  To the best of my memory it was about the same size as a softball but other than size was exactly like a tennis ball.

Monty loves to play fetch, but I think the regular size tennis balls are a bit small for him.  I worry that one of these days he's going to catch one badly and choke.  I think the bigger ones would also probably not roll under the couch, which would make me quite happy!

TIA
