2 Pool Noodles (Creve Couer)

I am requesting 2 long foam pool noodles to close the gap between a baby gate and the wall. The color does not matter but it would be best if they are free from damage. They will be near kittens and I don’t want to risk pieces coming off that could be swallowed.
The backstory:
I foster mama cats and kittens for the Humane Society. I am sectioning off a room of my house for the kitties to give them more space.
I managed to find a “baby gate” tall and wide enough to—-almost!—fully block them in and away from my pets.
There remains a small gap between the gate and wall on either side. It is just enough for a clever kitten to squeeze through.
I have the spaces temporarily blocked with rolled up blankets but would like something sturdier.
Thank you!
