Last year I hit something on T/O from Istanbul. (737-800)
We were doing about 110 kts, when I saw something, which I thought was a cat, running into the landinglight beam from the left. We were getting close to V1, continued the t/o.
Once airborne, I did my best to inform the TWR that we might have hit a cat during our T/O roll and that they should check the runway. After some initial language problems they said they would.
Later on during the flight we were informed by Sofia CTRL that IST had found a dead dog on the runway.
Turned out we had hit it with the left main LDG Gear. Not much damage at all, luckily. Wrote it up as a dog strike in the ASR .
